Normal cmyk ink is designed to be printed on white paper. This is all well and good but what if you want to use a coloured paper? Well, you can print cmyk on coloured paper but you do not get the true colour representation as you see the colour of the paper through the ink. A white ink underpin is needed.
White ink is essential when printing on coloured stocks and speciality papers and Ashwyk have mastered how to do it. Other HP Indigo printers may have the option to print white ink but it’s the skill and knowledge that is needed to get the perfect result. One shot technology is sometimes required whilst the number of hits can change depending on image coverage and stock type.
It’s something we do a lot and it’s a great tool to use. There has been a huge increase in the numbers of speciality papers that are now available from the likes of GF Smith, Fedrigoni and Antalis. Designers and end users are constantly looking for ways to increase impact on their marketing collateral or general brand and White ink on creative papers is definitely one of them.
