I am having trouble with my ORACAL® 631 releasing from the liner onto the application tape. What can I do to improve this?

There could be a couple of things happening with this situation. First check your vinyl plotter settings to make sure you aren’t cutting too deep into the release liner. If the silicone layer portion of the release liner is penetrated by the plotter blade it can cause the adhesive to migrate into the cut line. This creates an undesired bond between the release liner and the vinyl graphic. If this is consistent from one color to another, you may consider reducing the cut depth/pressure setting on the plotter. The idea should be to have the plotter blade cut through the face film and adhesive layers and barely score the surface of the silicone layer portion of the release liner. After applying application tape, place the graphic face down on a rigid table top so you are viewing the back of the release liner. Apply pressure with the squeegee back and forth several time over the back of the release liner. This will help push the adhesive out of the cut line and also create a stronger bond between the vinyl graphic and the application tape. It can be difficult to pull the graphic from the release liner, so it may be easier to remove the release liner from the graphic while the graphic is face down on a rigid table top. It is also important to use a high tack application tape such as ORATAPE® HT55 which was designed specifically for use with ORACAL® 631. If you need further assistance with troubleshooting please contact ORAFOL Product Technical Support directly.

Can ORACAL® graphic marking films vary in color from lot number to lot number?

Yes, for graphic applications of the same color on a single substrate, ORAFOL recommends using material from the same lot number. If materials from different lot numbers have to be used, the user must check prior to application whether any differences between the lot numbers will affect processing of the films and/or impair the final result.

At what temperature do I store my rolls of ORAFOL materials? Do temperature variations affect the vinyl film while still on the roll?

The self-adhesive products ORACAL®, ORAJET®, ORAGUARD®, ORABOND®, ORALITE®, Reflexite® and ORAMOUNT® are supplied in rolls and should at all times be stored either suspended or standing on end on the roll blocks provided, and never lying on the material's side. For storage and processing they should be kept in a cool dry place protected from sunlight. Relative air humidity between 50% and 60% and temperature between + 64°F and 72°F should be ensured. Direct sunlight, storage beside radiators, etc. should be avoided. Please observe the shelf life instructions contained in the technical data sheet available for each product.

Are there specific color profiles I should be using with ORAJET® materials?

Yes, make sure to load the correct media profile for your job, based on your specific combination of media, ink, printer and RIP software. Each series of ORAJET® digital media requires different print and RIP software parameter settings due to its individual qualities, such as thickness of the adhesive layer and face film.

Will my printed ORAJET® materials be warranted when using a liquid laminate to protect my prints instead of ORAGUARD® laminating materials?

No warranty will apply when combining any ORAFOL films with other manufacturers of pressure sensitive adhesive graphic marking films or liquid laminate coatings.

Does ORAFOL offer custom colors? Can you match a Pantone color?

ORAFOL can produce custom colors for most products, however there are minimum order requirements and possibly additional costs based on order volume. For specific inquiries, please contact your respective ORAFOL Americas Territory Sales Manager.

What type of laminate should I use for my prints on ORAJET® media?

ORAGUARD® laminating films are designed to match specific ORAJET® digital media. For specific recommendations, refer to the Digital Inkjet Media Selection Guide. When using solvent inks, we recommended allowing a minimum of 24 to 48 hours for the ink to cure before laminating. Failure to follow this practice can cause bubbles, delamination, discoloration, shrinkage and difficult application due to increased adhesive properties.

Can environmental conditions affect vinyl releasing from a liner?

All cut, weed, mask and release operations are subject to environmental conditions. High humidity and heat conditions can make application more difficult. In these cases a higher tack application tape(such as ORATAPE® HT55)may help. If plotted graphics are not weeded quickly after production, adhesive may flow into the cut line, making weeding more difficult.

I want to know if ORAFOL films contain acid because I want to use the vinyl for my scrapbooking projects.

No, ORAFOL films do not contain acid. They will work great for your scrapbook projects.

Does ORAFOL offer stencil mask films? If so, are any of them translucent?

Yes, ORAFOL Americas offers 4 different stencil mask films…ORAMASK® 810, 810S, 811, and 813. ORAMASK® 810 is a conformable stencil film that is useful for spraying and painting on uneven surfaces. It comes in a transparent grey color. ORAMASK® 810S has a solvent-based adhesive that is ideal for multi-color or solvent-based paints. It is highly conformable and comes in transparent grey. ORAMASK® 811 is a rigid paint mask film for painting or spraying on even surfaces that is available in opaque white. Lastly, ORAMASK® 813 is a translucent rigid stencil film for painting or spraying on even surface areas that is available in translucent blue.

Can I clear-coat ORAFOL vinyl graphics?

Clear-coating materials such as liquid laminate may provide additional protection for vinyl graphics, but caution should be used because solvents in some varnishes can attack the vinyl and/or adhesive, causing failure. When in doubt, use the matched ORAGUARD® cold laminating films.

Can I print on ORACAL® brand films with a thermal-transfer printer?

Many ORACAL® plotter films including Series 651 and Series 751 are engineered to perform well with thermal-transfer printers.

What ORAFOL media can be used with dye and/or pigmented inks?

ORAFOL does not currently market films designed for use with water-based ink sets.

What pressure should I have my vinyl cutter set on when plotting ORACAL® vinyl films?

There are many different types of plotters in use. You should run a test to ensure that your blade pressure and speed are properly adjusted for ORAFOL's higher density films. When testing different pressure and speed settings, look for how easy the graphic weeds, making sure not to cut too deep. Also, make sure that the vinyl cleanly releases from the liner using transfer tape. If cut too deep, the vinyl will be difficult to release from the liner, and may cause tearing along the edge of the cut.

What application tape do you suggest when using ORACAL® plotter films?

We recommend a high tack application tape, such as ORATAPE® HT55 for most of our plotter films. The relationship between the release liner and the vinyl is different for every vinyl manufacturer. ORAFOL’s vinyl has a tight liner adhesion. The tight liner adhesion improves the weedability of the vinyl. If what you’re using works for you, continue to use it. Other tips we suggest include squeegeeing on the reverse side (the back of the liner) and pulling the release liner away with the application tape side down.

Will ORACAL® films work on my plotter?

Check the technical specifications for the ORACAL® Series that you are interested in purchasing to see if it is compatible with your brand of plotter. You may also want to run a test cut to ensure that your blade weight is properly adjusted for ORAFOL’s higher density.

Are ORAFOL's films enamel receptive?

Many enamel coatings, as well as airbrush paints, bond well to ORAFOL films, but we recommend testing your specific brand of paint. KRYLON® enamel paints tend to work very well. One Shot® paints require the use of One Shot® Vinyl Primer.
