Inks

High-quality, low tack printing inks should be used, preferably unreduced. The ink must not react with the coating; if in doubt, please consult your ink supplier. When printing on the reverse side, use thinly applied light-coloured inks (no glossy inks).

Offset

When selecting offset printing plates, make sure they are suitable for printing on carbonless paper. They should allow minimal water passage, and the rubber blankets should be compressible. Exercise great care when using dampening solution additives, as they can cause discolouring or reduce the legibility of copies. The proportion of alcohol added should not exceed 15%, and the pH should be kept at 5.5.

Small Offset

When using small offset presses, it is advisable to run the paper through the press with its grain perpendicular to the cylinders (long grain). This will enhance running stability.

Processing Tips

Cutting

When using guillotine-type cutters, the following must be observed:
• Keep the clamp pressure as low as possible
• Slipping of the stack and discoloration can be avoided by attaching a 20 mm thick section of expanded rubber to the clamp.
• Remove protection sheets before cutting the ream.
• Ensure that the guillotine blade is sharp.

Desensitising

Supreme Image desensitising inks are specially matched to the reaction system of the Supreme Image paper. No guarantee can be given if other inks are used. It is suitable for wet offset (also suitable for letterpress and dry offset after adding 2% print oil).

The above instructions are a guide only and testing prior to running the job is always recommended. Please contact Stockman Paper Merchants if further details are required.
