The Why and How of Artwork Pre-Distortion for Shrink Sleeves

Branding without shrink sleeves has become unimaginable. A well-designed and properly executed shrink sleeve application promises enhanced brand recognition, recall and visibility for your products on cluttered shop shelves.

However, it is crucial to understand the possible and often staggering setbacks you could face if you do not consider the effects of shrink distortion on your artwork design.

 

The Dilemma of 2D VS 3D

The shrink sleeve making process is pretty straightforward. It starts with designing the artwork and transferring it to the film via printing. The film is joined together and placed over the destination container or bottle. Next, it is time for the heat tunnel where the sleeve gets shrunk to fit around and onto the bottle.

 

What could go wrong?

Since the printed artwork is 2D and its execution is in 3D, there are high chances of the artwork becoming distorted and looking different from the intention. Hence, the need for pre-distortion of graphics comes up.

 

Pre-distortion to The Rescue

During the graphic pre-distortion stage, keep in mind the shape of the container and how much shrinkage is typical for the chosen material.

Until recently, pre-distortion was primarily a manual and experimental task that required multiple rounds of revisions, causing massive delays.

Thankfully, massive R&D in this field has brought about state-of-the-art 3D rendering technology to visualise the expected shrinkage.A good case in point is the advanced Distortion Prediction Technology™ we use at Taurus Packaging.

It allows us to visualise the container in 3D and how the graphic will appear after the expected shrinkage. Once everything is checked, the pre-distortion gets done.Next, the rendered ARC™3D image of your sleeved container shows how the sleeves would appear in real-time.If everything is on point, the design is ready to be printed.

 

Closing Thoughts

Artwork pre-distortion is a crucial step that must get incorporated into your shrink sleeve development process. Distortion prediction allows graphics and text to appear flawlessly on products so you can make good branding decisions before going for commercial approvals.

What is PCR and The Shift Towards PCR Plastics

In a previous article on Extended Producer Responsibility (EPR), I have discussed the responsibility of brands to recover, recycle, reuse, and dispose of the products they produce. And how they need to innovate their waste management initiatives.

Now, what if you could shift to packaging made from recycled materials? Such a step could help you preserve the environment, stop depending on consumers to recycle after use, and cater to shoppers who favor sustainable brands.

This is the crux of PCR!

What is PCR?

The term PCR refers to Post-Consumer Recycled (reprocessed) plastic, primarily manufactured at recycling plants from items that consumers have, in a way, already recycled. Hence, PCR plastic is clean plastic that needs no further recycling. Since PCR plastic comes from reprocessed or post-consumer plastic waste, it reduces the load on landfills – which is a big PLUS.

 

Sustainable Packaging With PCR

PCR packaging film is a sustainable packaging alternative. It is made using the reprocessed PCR plastic which is derived from recycled materials like plastic bottles, cardboard boxes, and aluminum, etc.

Hence, it is a much better alternative to virgin plastic derived from non-renewable resources like natural gas, putting a strain on our environment.

 

Benefits of PCR Plastic And Its Usage

 

POSITIVE IMPACT ON THE ENVIRONMENT: Unlike virgin plastic, post-consumer recycled plastic is gentle on our planet. Since plastic waste gets rooted in recycling facilities, PCR plastic helps reduce toxic plastic waste that piles up at landfills.

 

STEP TOWARDS SUSTAINABILITY: There is a consistent rise in the number of shoppers and consumers sensitized about preserving the environment for their future generations. These individuals are making conscious efforts to buy from brands with strong sustainability goals. Hence, using PCR materials for your packaging needs will help you become more sustainable and tap into this growing consumer base.

 

FLEXIBLE PACKAGING MATERIAL: Today, PCR packaging films are being used to fulfill packaging needs across all major industries, including pharma and food. It is a flexible material that meets and passes all kinds of stringent quality checks.

 

CLOSING THOUGHTS

Today, companies worldwide are taking their sustainability goals seriously and recognizing the importance of reducing their carbon footprint. In this context, the shift towards PCR plastic materials is a welcome move. Though still in its early stages, it will be interesting to see how well brands adapt to this change and include post-consumer recycled plastic and packaging for their products.

The Importance of Colour-Matching in Printed Packaging And How To Do It?

Colours form the heart and soul of print designs. So it is no wonder that brands spend a lot of time and attention selecting the correct colour scheme for their product’s packaging. However, the work does not stop here as it’s equally important to bring the design to life, exactly, the way it looks on the computer. Any mismatch and the printed design may appear far different from the intention, leading to unavoidable delays and unnecessary panic. It is here that the concept of color-matching comes in.

What is Colour Matching?

Simply put, colour matching refers to making sure that the colours in your packaging design, visible on screen, look the same once the design gets printed and takes its place on the final product. Hence, color-matching is crucial in printed packaging. It not only helps to maintain colour accuracy in terms of its hue, brightness, and saturation but avoids last-minute surprises and deviations from the intended result.

Ways to Achieve Colour Correctness in Printed Packaging

 

1.  Start Designing in the Most Appropriate Colour Space

Colours get represented differently in different colour spaces. Hence, to get desired results, it is recommended to work in the correct colour space right from the beginning. It means that you may have to go beyond the default colour profiles on your system, such as sRGB, and install the one most appropriate for your projects like Adobe RGB or CMYK.

2. Use Proofing Tools to Generate a Soft-Proof of Your Designs

Before you spend time and money printing the hard-proof of your design and being disappointed with the results, go in for soft-proofing using a calibrated monitor. An electronic-screen soft-proof is a highly beneficial alternative to get a sense of what the design and colours will look like upon printing and whether or not you’re on the right track.

3. Don’t Forget the Physical Print Proofs

After checking the artwork on your monitor, it’s time to get a digitally-printed physical proof of the design. Though it may seem unimportant, it is, in fact, the hard printed proof that helps to spot problem areas and possibly foretell inconsistencies that may crop up in the final version the printing press sends you and avoid them beforehand.

 4. Communicate Your Expectations to The Printer

It is always good practice to brief your printer about your expectations correctly, especially when they’re about to tackle large runs, tricky print jobs and complex reprints. So do provide them with colour matching samples, reference prints, and colour mixing references to maintain colour accuracy & reduce time wastages in corrections.

5. Ask for Cylinder Proofs

Most printers and consumers depend on cylinder proofs for print approval since they give the right colours up to a certain extent. However, cylinder proof does have its limitations.

  • The cylinder manufacturer must be using the same film and inks to match the proof, or there will be a deviation.
  • Proofing is done with high viscosity inks, whereas in printing, viscosity is lower, which can produce variations between the proof and the actual print run.
  • Proofing happens at a much slower speed than the actual commercial speed of printing. Slow speed would mean there would be a difference in dot transfer, thereby affecting the colours.

Though cylinder proof is a sensible parameter to check the print job, it can differ from the actual result. Hence, do keep a certain tolerance for colour shades in mind when relying on cylinder proofs.

6. Opt for a Colour Library

If you need special or uncommon colour profiles for your print packaging, you might want to consider working with a colour library such as Pantone or CMYK equivalents. For one, you will have access to a full gamut of colour references. And two, maintaining colour accuracy and representing your brand correctly will no longer be challenging.

7. Use Extended Colour Gamut Printing (ECG)

Extended Colour Gamut Printing is the methodology of introducing three additional inks, Orange, Green & Violet (OGV), to the CMYK Process Colours, Cyan, Magenta, Yellow, and Black during printing. Adding the extra colours extends or expands the range of colour printing and helps to reduce the overall dependence on spot colours. The resultant printed images are a lot more vivid with negligible colour difference.

8. Pay Attention to the Lighting

Whether you’re approving proofs or colour matching, it is crucial to have the correct lighting since even the slightest variation in your light source can change how visual is perceived. So try to maintain standard lighting conditions as that goes a long way in avoiding faulty approvals and perception-related glitches.

According to the International Standards Organisation ISO 3664, you should view and approve prints under a D50 equivalent light source.

 

CLOSING THOUGHTS

A little planning and forward-thinking goes a long way to complete the printing project without delays, rework, and glitches. And ensuring that you get your printed colours right and in perfect sync with the intended results.

How Shrink Sleeves Affect PP Container Recycling

In our previous article, we talked about the effect of shrink sleeves on PET bottle recycling. In this article, let’s look at how PP containers react to recycling when shrink sleeves stay attached to them.

PP or Polypropylene is a type of plastic commonly used to manufacture food containers utilized in packaging takeaway food items and beverages, etc.

Though PP containers are recyclable, certain film substrates interfere with the recycling process if they are left attached to the containers. That’s why businesses must know which shrink films are best for proper recycling and the correct procedures to follow during PP container recycling.

 

Selection of a Film Substrate

Compatibility: Some sleeve label materials have a density of <1.0 and thus float in the float/sink tank, remaining with the PP. This material cannot be removed during the recycling process. Hence, it can contaminate the recycled PP if not compatible with the PP.

 

What’s the Solution?

  • Films compatible with PP recycling sink in water and can separate from the PP floating in the water. That’s why a preferred choice is to use full bottle sleeve labels specifically crafted for automatic sorting.
  • Considering that a full bottle sleeve gets attached to the full surface of the bottle, leaving only a small portion uncovered, we must select a material compatible with automatic sorting, or the sorter machine may segregate the PP bottle with the wrong materials destroying it.
  • Also, PVC material needs strict avoidance as even a trace amount can contaminate the reprocessed PP.

 

Label Inks

The type of ink used on sleeve labels of PP containers also has a bearing on their recyclability.

For example, certain types of label inks bleed during the wash step of the recycling process. If the PP container catches on to the ink color, it becomes discolored, making it even more difficult to salvage the PP and turning it reusable for various intended purposes.

 

What’s the Solution?

  • It is recommended to select inks with the correct density, so they stay on the label during the wash process.
  • And do not bleed and mix with the water.

 

Why Using Pressure-Sensitive PP/PE Labels is Detrimental for PPRecycling?

When recycling a PP container, it is important to know how a certain film substrate will behave in contact with water.

Will the adhesive used to secure the label give away and release the label or will it keep the label held on to the container? In other words, will the label sink or float?

Hence, it is here that testing the adhesives to see how they react becomes crucial. Either the adhesive must be well suited to the PP or it should come off hassle-free during the wash process.

If not, and even the slightest traces of the adhesive stay, it will discolor the recycled PP, spoiling the end result.

 

Model Specifications – Shrink Sleeve Labels for PP Bottles

 According to the Association of Plastic Recyclers (APR), here are the identified characteristics considered compatible with PP recycling –

 Full Compatibility: Sleeves PETG with density >1 g/cm³, and with a size that does not hinder the recognition of the underlying PP-polymer.

Limited Compatibility: Sleeves in PVC, PLA, PS (all with density > 1 g/cm³)

Low Compatibility: Sleeves that hinder the recognition of the PP; Sleeves in non-PP-materials with density < 1 g/cm³; Aluminium/Metalised Sleeves; Heavily inked sleeves

 

CLOSING THOUGHTS

Considering that plastic continues to be frequently used in packaging and requires proper recycling, it is the responsibility of businesses to be conscious about their choices.

The future may see us joining hands with label suppliers who offer recycling-compatible sleeves for their products. But until then, it is on us to do our bit towards a cleaner, safer environment for us and our future generations.
