Permaprint Premium Poster Ink Process Colours
Permaprint Premium inks are high-quality, water-based screen printing inks primarily suited to printing posters and other hard surfaces. Manufactured in Australia, they are 100% solvent free, making equipment easy to clean with water.
The process ink range is a series of semi-translucent colours perfect for use in 4-colour halftone printing. If you need help experimenting with and understanding process printing, we recommend attending our Preparing Artwork for Print Class or Paper Printing for Beginners to learn more about creating halftone images and printing them.
Permaprint Premium inks dry glossy and offer excellent weather resistance. After air drying, prints exhibit excellent abrasion resistance and good water resistance properties which make them useful for printing posters and signage, though not ideal for textile surfaces which will be repeatably washed or stretched. See the Permaset Aqua range of inks if you intend to print fabrics and textiles.
Suitable Substrates/ Print Surfaces:
Permaprint Premium inks are suited to printing onto paper, cardboard, tyvek, polyesters (mylar), polycarbonates (lexan), some coated metals and poly-styrene. Care should be taken with some vinyls as plasticizer migration may soften the ink over time. Care should also be taken with some uncoated papers as cockling may occur.
Screen meshes of 70-120T (180-305 tpi) monofilament polyester are suitable for most Permaprint Premium applications. Normally one to two pulls of the squeegee are required when printing. If using stencils, ensure they are water resistant and fully cured. Always replace the lid after use to avoid the ink drying out and changing viscosity.
Permaprint Premium inks dry by evaporation over 20-30 minutes depending on the ambient temperature and humidity. If only air-dry facilities are available, do not apply if temperature is below 10 degrees Celcius (50 degrees Fahrenheit). Prints may be jet dried at 65-75 degrees Celcius for approximately 30-40 seconds using maximum air flow. Ensure adequate ventilation is provided and cooling allowed before stacking to prevent sticking or blotting.
*Important*: Before attempting any print run, experiment with pieces of test material to check adhesion and water-resistance properties. If using a tunnel drier, run a number of full sized test blanks through, both before and following the test print, to simulate thermal load.
Storage and Handling:
USE ONLY IN A WELL VENTILATED AREA.
Handle according to good industrial hygiene and safety practices. Store in a secure place, out of reach of children. Store in a cool dry place out of direct sunlight and away from sources of heat. Protect from freezing.
Not an inhalation risk. If ingested, immediately rinse mouth out, drink plenty of water and seek medical attention. Repeated or prolonged skin contact may lead to irritation and it is recommended that any skin contact should be avoided by wearing gloves. If contact occurs, wash skin immediately and thoroughly with soap and water.
Safety and Handling:
PermaPrint Premium has been formulated to be free of any toxic chemicals. The range has no flash point, and as such is exempt from Flammable Liquids regulations. Comprehensive information on the safety and handling of products in the PermaPrint Premium range of inks and ancillaries is provided in the appropriate Safety Data Sheets (SDS) which are available on request.
