Hydrochromic inks

Posted on Wed, 5 Feb 2003 at 16:15



Looking for an ink that appears white when dry but becomes temporarily transparent when moistened
Recently saw a product produced in the UK.
The ink was silk screened on an offset printed sheet that had an overall UV coating.
The ink appeared white but when moistened it temporarily became transparent (invisible) but reverted to white as it dried.
Would appreciate any info on a source for this ink product.
