When deciding how to execute a printing project, you have several options. The three main categories we utilize are digital printing, offset printing, and flexographic printing. Each has its specific characteristics, advantages, and disadvantages. Let's find out which one is best suited for your needs.
 

​

Digital Printing

Digital printing allows us to print directly from a computer without the need to prepare printing plates. We use it for small and medium runs when clients require rapid delivery. Its main advantages are:​

• An excellent choice for projects where speed and flexibility are essential.

• A wide range of printable materials (paper, metallic, white and transparent films, combined barrier materials for flexible packaging, etc.).

• Suitable for small series.​

HP Indigo WS6600 Digital Press Takes It Even Further

It offers efficient and high-quality product presentation with perfect image and consistent colors, even for low-volume runs. HP Indigo has everything you need. Its main advantages are:​

• Frequent design changes are not a problem.

• Zero costs for design changes.

• Small and medium orders with a multitude of label variations.

• Variable print data – serial numbers, EAN and QR codes, graphic elements.

• No waiting – you get express delivery.​

Offset Printing

Offset printing operates on the principle of transferring an image from a printing plate to the substrate using a rubber-covered transfer cylinder, known as the offset cylinder or blanket. The process step by step is as follows:​

1. Preparation of the printing plate: The plate is usually a metal sheet with printing and non-printing areas.

2. Before applying ink, the plate is moistened with a solution of water and additives. This adheres to the non-printing areas, which repel water.

3. Ink is applied to the plate using ink rollers. The ink adheres only to the printing areas, which are oleophilic, as water on the non-printing areas repels the ink.

4. The image from the plate is transferred to the offset cylinder (blanket) covered with rubber.

5. From the offset cylinder, the image is transferred under pressure to the substrate (paper, film, etc.).​

Advantages of Offset Printing

• Excellent print quality with accurate colors.

• Ability to use special colors (metallic shades, precise colors according to PANTONE).

• A suitable solution for high-volume runs (thousands of pieces).​

Preparing printing plates for offset takes some time, but the result is professionally looking printed materials.​

We choose offset for demanding projects – it's intended for clients who require stable label quality even for million-piece runs. Offset is also used for printing catalogs, magazines, books, or representative corporate materials in large volumes, where quality and color fidelity are paramount. However, remember that it's mainly limited to paper and some films.​

Heidelberg Speedmaster Simplifies the Entire Process

The Heidelberg Speedmaster meets all the demands of the current market. Thanks to extensive automation of the printing process, it is cost-effective even for smaller orders. For high-volume runs, its fast and stable production truly shines.​

Flexographic Printing

Flexographic printing is a printing technology that uses flexible photopolymer printing plates. Our brand-new Soma Optima machine is ideal for printing on flexible packaging materials, paper, or laminate from roll to roll. It features the following advantages:​

• High-quality printing even on thin and flexible materials.

• A broader spectrum of printable materials (paper, films, laminate).

• Suitable for large volumes and long runs.

• Efficient printing, especially for packaging and labels.

• Ability to print with UV inks for high gloss and durability, as well as with solvent-based and water-based inks.

• Accurate color reproduction thanks to CNC positioning and an automatic register adjustment system.

• High production speed.​

Additionally, the Soma Optima is equipped with advanced features – a central cylinder with thermal stabilization, which prevents material wrinkling or stretching, and doctor blade chambers that ensure even ink application. Efficiency and speed are further enhanced by an automatic washing system.​

How many times have we bought a product in a store just because it had an eye-catching label? Self-adhesive labels can grab a customer's attention and influence their purchase decision. But do you know how these labels are made and what options they offer?

What are self-adhesive labels?

Self-adhesive labels are a special type of label that differs from traditional ones in their method of application. While traditional labels are affixed to products using glue or other attachment methods (e.g., placed inside packaging), self-adhesive labels have an adhesive layer on the back, making them easy to stick to almost any surface.

Advantages of self-adhesive labels:

• Easy application – just peel the label off the backing and stick it to the product, no glue required.

• Flexible shapes – they can be cut into rectangles, circles, ovals, or custom die-cut shapes.

• Material versatility – a wide range of papers and films, with various surface finishes.

• Edge-to-edge printing – full-color, borderless print thanks to die-cutting on silicone liners.

• Durability – high resistance to moisture, chemicals, and abrasion when using plastic materials and lamination.

• Added features – optional perforations, coupons, variable data (e.g., QR codes, serial numbers), and security features like holograms or tamper-proof materials.

Production process of self-adhesive labels

It all begins with the graphic design. The goal is to create a visually appealing and informative label that grabs attention while meeting technical requirements for print.

The next step is choosing the right material – this affects the print quality, label durability, and its performance under various conditions.

At Aluprint, we use a range of printing technologies to bring label designs to life:

Offset printing

• Ideal for large-volume jobs.

• Delivers high-quality print results.

• Machines like the Heidelberg Speedmaster are also efficient for smaller jobs.

UV offset printing

• A hybrid combining offset and flexographic benefits.

• Enables double-sided printing and speeds of up to 200m/min.

Flexographic printing

• Suitable for printing on flexible packaging materials, paper, and laminates.

• Offers precise print control and consistency.

Digital printing

• Best for small to medium runs.

• Allows for personalization and variable data (serial numbers, QR codes, etc.).

• Enables frequent design changes with no extra plate costs.

Common mistakes in label design

Even though label design might seem easy, many common mistakes can compromise the final result.

1. Incorrect material selection

Choosing the wrong material can lead to early wear or functional issues.

• For moisture exposure (cosmetics, refrigerated items): use plastic films like PP, PE, or PVC or laminated paper.

• For extreme temperatures (frozen goods, automotive): opt for aluminum or thermostable synthetics.

• For abrasion (shipping labels, heavy-duty use): choose strong materials with lamination or UV varnish.

2. Wrong dimensions or shape

A poorly sized or shaped label looks unprofessional.

Avoid:

• Labels too small or large for the product surface.

• Not considering curves or uneven surfaces.

• Blocking key package areas (openings, seams, instructions).

• Mismatched shapes (e.g., oval label on rectangular packaging).

3. Overloaded design

Trying to cram in too much info makes the label chaotic and unreadable.

Avoid this by:

• Including only essential visuals and text.

• Leaving sufficient white space.

• Using a consistent style and 1–2 fonts.

• Clearly organizing elements by priority.

• Highlighting key aspects (logo, product name, USP).

4. Inappropriate color selection

If the printed colors differ from your brand or design preview, the product’s impression suffers.

Causes include:

• Using incorrect colors during file prep.

• Not accounting for color gamut differences between screen and print.

• Ignoring how label materials affect color appearance.

• Not setting correct ICC color profiles.

• Inconsistent color tones across one label batch.

5. Missing legal requirements

Labels must meet legal standards for product info. Missing mandatory data can lead to fines or product recalls.

Mandatory info often includes:

• Product name and description

• Ingredients or material composition

• Weight or volume

• Manufacturer or distributor info

• Expiration or best-before date

• Health or safety warnings

• Instructions for use or storage

Creating self-adhesive labels requires experience, technical know-how, and attention to many details. Don’t leave it to chance – trust the experts.

Have you ever wondered what drives a customer to choose your product in a store? While brand loyalty often plays a role, what happens when someone picks an entirely new product? In many cases, it’s the design of the label that motivates the choice amidst dozens of similar options on the shelf.
 

The importance of label design

A compelling label design is crucial for grabbing the customer’s attention and influencing their purchasing decision. A label has only a few seconds to make an impression and convince the buyer of the product's quality and value. A well-designed label can evoke emotions, communicate essential information, and differentiate a product from its competitors. But why does the same product sell better with one design over another?

1. Legible labels

A label must be easily readable, even from a distance. To achieve this, focus on:

• Contrast: Ensure sufficient contrast between text and background by selecting complementary colors.
• Font Size: Key details like the product name and brand should be significantly larger than supplementary text.
• Font Style: Use clear, simple fonts without unnecessary decorative elements. Sans-serif fonts are often a good choice for primary text.
• Spacing: Leave enough space between lines and sections to avoid a cluttered appearance.

2. Attractive graphics

Visual elements such as images and graphics enhance the text on a label. They can grab attention, distinguish your product from competitors, and evoke the right emotions in customers. Consider:

• Illustrations and Photos: For instance, juices are often associated with fruits, while sparkling water evokes bubbles. Always work with experienced graphic designers who understand current trends.
• Icons, Shapes, and Symbols: These elements should harmonize as a cohesive whole, support the brand message, and avoid being distracting. With today's printing technologies, even the finest details can be achieved.
• Colors: Colors evoke emotions and associations with specific qualities. Beverages may use vibrant hues, while cosmetics might opt for softer or premium tones with matte finishes.
• Placement: Graphics should complement the text rather than overshadow it. For wrap-around labels, ensure the design flows seamlessly across joins.

3. White space

White space—or "negative space"—is an essential design element that:

• Highlights important features like text or graphics.
• Creates balance and harmony.
• Guides the customer’s eye to key areas.
• Adds an air of sophistication and premium quality.

Avoid filling every millimeter of the label. Allow text and graphics to "breathe," giving them room to stand out. For example, leaving empty space around logos or product names emphasizes their importance. And this applies to smaller self-adhesive labels as well, not just the large ones.

So, don’t be afraid of empty space—use it intentionally. It will make your label more appealing.

4. High-quality materials

The tactile experience of holding a product often speaks volumes about its quality. Customers subconsciously assess whether they’re handling a premium item or just another generic product based on:

• Material Choice: Opt for substrates that feel pleasant to touch and look high-quality. For beverages, waterproof films may be suitable, while luxury papers work well for cosmetics.
• Printing Effects: Modern printing technologies can apply embossed stamping, metallic colors, glossy or matte laminations, as well as spot UV coating, even on cut and die-cut labels.
• Product Fit: The material and finish should align with the product type—for instance, an exclusive gin bottle versus a carton of fruit juice.

5. Strategic layout

The arrangement of elements on your label should guide the eye naturally from the most important information to secondary details:

• The product name and brand must be prominent and instantly visible.
• Highlight key attributes like "non-GMO," "vegan," "gluten-free," or "sugar-free" immediately after the name and brand.

This hierarchy ensures that customers quickly grasp what sets your product apart.

 

Designing labels may seem complex at first glance, but it’s an art we’ve mastered over 31 years of collaboration with renowned brands like Coca-Cola, Mattoni, Kofola, and others. By combining thoughtful design principles with modern printing techniques, you can create labels that not only look great but also drive sales.

17. March 2020Current situation due to the Coronavirus

Preventive actions against the spread of Coronavirus                                                

      Because your employees, or employees of the companies you work with, come into contact with our employees, we ask you to inform them about our company requirements as a preventive action against the spread of coronavirus.

      Fulfillment of these requirements will be strictly required and their non-compliance may be a reason for non-acceptance or non-production of goods.

      All visitors entering Aluprint s.r.o. premises are obliged to respect the following rules:

• Comply with the general regulations of the Government of the Slovak Republic in connection with the COVID-19 pandemic according to the continuous update
• Prohibition of any visits outside the service department of suppliers of machinery and equipment, who at the time of the visit follow the instructions of the production manager or the person directly authorized by him
• In the case of admission to the premises, the visitor must be wearing a protective mask and gloves before entering the premises and must use them throughout the visit.

• Unless the presence of drivers is required during loading and unloading of the vehicle, driver has to to stay in the cab
• Do not enter buildings
• Refrain from shaking hands or other forms of personal contact
• Follow the instructions of Aluprint s.r.o. employees

      We would also like to inform you that, as part of our internal guidelines for preventing the spread of COVID-19 issued to our employees, we have introduced the following restrictive actions in addition to the introduction of hygiene rules:

• We have introduced a "home office" for employees where their performance of their duties allows it
• We are gradually increasing the stock of raw materials to ensure the operation from the 1-month maximum to the 3-month maximum
• We allowed dispersal of work shifts in workplaces with one-shift operation also for further work shifts, so that the concentration of workers in one workplace or production hall is minimal (less than 5)
• We enable our customers to produce higher quantity and to use our stock in order to reduce the risk of non-delivery
• No smoking, even in areas previously designated for this purpose
• Prohibition or restriction of all activities related to the gathering of people (suspension of the project of training employees using the EU funds, cancellation of audits, limitation of the number of meetings and their occupation, etc.)
• Prioritizing employees' own meals over meals delivery services

We believe that our active approach will help to minimize the impacts.

We will deal with this situation together.
Stay safe and healthy.
