PROCESSING
Mix the ink with the PLH catalyst in a ratio of 4:1 (4 parts ink to 1 part of catalyst). For transparent colors and the transparent base, the ratio is: 3 parts ink and 1 part catalyst. Mix and strongly dilute the ink by using the PLA thinner in the measure of max. 10-20%. When printing fine details or screened images (e.g. 80/120 lines per cm^2) in warm environments, we recommend you add the PLD retardant in a minimum percentage. It is also recommended to use the ink about 15 to 20 minutes after the addition of the catalyst.
CAUTION!The catalyzed ink must be consumed within 6-8 hours or afterwards it gradually loses its mechanical-chemical resistance and its ability to adhere to the support. For uniform production quality it is advisable to renew the ink approximately every 4/8 hours of work. Excessive dilution generates a loss of the covering power, smudges and an imperfect detachment of the ink from the pad. An insufficient dilution causes problems of drawing the ink from the cliché, printing repeatability and dripping of the ink with a consequent decline of the printing quality.
DRYING AND HARDENING
The drying time lasts between 10 and 15 minutes at an ambient temperature of about 20°C. If you would like it to dry in only a few time, you can use hot air circulation ovens (60-80°C) or high temperature spot devices (air or infrared rays) that can be installed on the piece feeding systems (e.g. rotary tables, conveyors, etc.). The ink is completely hardened after 5-6 days.
