Printing on Cast Coated

As the coloured surfaces of Cast Coated Energy, Instinct, Monochrome and Soft Tech vary depending on whether they are protected with a non-absorbent lacquer or are conventional cast coated, the printing method required may be different.

Lithographic printing

Inks
Only inks that dry fully by oxidation must be used when printing the gloss side of the Cast Coated quality. The reverse side of Cast Coated has a lick coating and is capable of accepting four colours using conventional ink for Matt coated papers. If a solid or dense image is being printed, at least 48 hours should be allowed before printing the top side.

Damping
Cobalt acetate drier added to fount water is recommended the damping should be reduced and maintained at the lowest possible level; excess fount will retard or prevent the ink drying. Printing of Cast Coated on small offset machines incorporating an integrated damping system is not recommended.

Spray powder
Always use a non-vanishing spray powder.

Stack heights
These should be reduced to allow for the ink oxidation process to occur.

Finishing and other processes

Folding
Provided the material is correctly pre-creased, no problems should be experienced.

Lamination
Orientated Polypropylene (OPP) or Acetate films give good results, but the laminator should be aware that any solvent in the adhesive must be fully evaporated before the film comes into contact with the Cast Coated, as these can attack the surface. Cast Coated can be laminated using a water based adhesive without difficulty.

Foil blocking
The smooth surface of Cast Coated is excellent for foil blocking. Suitable foils are available and should be tested to confirm compatibility

Die stamping and blind embossing
Cast Coated is perfectly suitable for conversion by these processes.

UV Litho printing
UV cured inks and varnishes print satisfactory, but check with your ink supplier to confirm compatibility.

Screen printing
As long as the inks and additives do not contain any solvents which will attack the surface, no problems should occur.

Thermography
Good results have been achieved using thermography.
