The Difference Between Cast and Calendered Vinyl

When working with adhesive vinyl there are two types of vinyl film you can choose: Cast and Calendered.

Cast Films

Cast Films are a premium-grade vinyl that starts life as a liquid, which is then spread out to an extremely thin layer.  Cast films will not noticeably shrink and will conform to irregular textures and curved surfaces, making them the best option for the most extreme outdoor applications – especially vehicle wraps.  Cast Vinyl provides vibrant, paint-quality color and the highest level of durability, lasting for years.

Calendered Vinyl

Calendered Vinyl begins as a lump of plastic that is then flattened by being passed through two pressure rollers.  Though not as high-quality as cast films, calendered film is adequate for less demanding conditions.  Calendered films come in two types: Polymeric and Monomeric.


Polymeric calendered films have added polymers to reduce shrinkage, so they will fare much better in exterior applications than monomeric films but are not suitable for application over irregular surfaces.  For less demanding exterior work such as transit graphics that are frequently changed, polymeric films offer a workable alternative to cast.


The least expensive vinyl film is monomeric calendered.  Over time these films will shrink, collect dirt, and eventually curl up and flake off.  Monomeric films are best suited to short-term exterior applications or interior work.

These vinyl films can last anywhere from 6 months to 5 years or more, so it’s important to give us all the parameters of your install.  Talk to a GH Sales consultant or submit a QuickQuote so we can recommend the right vinyl for you.

4 Preflight Steps to Take Before Sending Large Format Print Files to GH Imaging

Before sending a file to GH Companies to be printed, there are some steps you should take to ensure that your file can be used for printing. These simple steps help ensure your art will be printed the way you intended it to and will also help expedite the printing process of your job.

Convert all Fonts & Text to Outlines

This is very important because if you don’t, it can cause your fonts to crash when the file is opened and be replaced with a computer’s default font.  Creating outlines guarantees your art and text will look exactly as you intended them to look. This can be achieved in Adobe Illustrator by selecting Type > Convert to Outlines (CMD + SHIFT + O mac or CTRL + SHIFT + O pc) while all the live text is selected. This changes the text into vector shapes instead of type. It will no longer be editable.

Art is CMYK

Ensure that the color of every part of your art is in CMYK color mode.  If colors are in RGB they will have to be converted which can result in an undesired change in color. This can be determined in Adobe Illustrator by selecting File > Document Color Mode and ensuring CMYK Color is checked.

Convert Strokes to Outlines

If using strokes in your design, convert your strokes to outlines.  That way, if your image needs to be resized it will still look the way you intended. This can be done in Adobe Illustrator by selecting Object > Path > Outline Stroke.

Embed All Images  

This saves the images into your file, ensuring that the computer can find it.  If not, the computer will replace the image with a blank box. This can be achieved in Adobe Illustrator by selecting the "Embed" button at the top bar of the file while the image is selected.

These simple steps will ensure that we can use your file and print your design exactly as you envision it.
