Pop’Set papers and boards give excellent printing results with all major print processes.  To optimise your print results, we offer some recommendations:

Design and pre-press

• ·   A screen of 133 -150 lpi should be used.
• ·   Finer screens up to a maximum of 200 lpi can also give very good results with careful ink density control. For dark 4 colour images with high ink density, under colour removal may be required depending on the visuals.
• ·   Aim for the total ink film weight of 260%.

Printing inks

• ·   Conventional, positive drying inks should be used with or without infra-red drying assistance.
• ·   UV inks may also be used.
• ·   Avoid using overnight / stay fresh / duct stable inks.   
• ·   Always allow sufficient drying time.
• ·   Use laser stable inks for subsequent laser printing.
• ·   It is always advisable to consult your ink supplier about specific projects to ensure ink suitability

Paper handling

• ·   To help avoid marking and set-off when printing multiple colours, 35micron anti set off spray for boards and 20micron for paper weights are recommended.
• ·   It may also be helpful to turn off the delivery stack joggers and restrict the delivery pile height particularly when printing boards.
• ·   Always protect paper from environmental humidity and temperature changes by using stack covers or stretch wrap. 

Sealers and coatings

• ·   Sealers and press coatings can be used to help reduce marking for further operations. 
• ·   Ensure the inks are suitable and best results are achieved when the inks are dry before sealing.

Varnishing

• ·   To achieve a gloss varnish, it is essential to pre-seal the surface with Silk screen applied matt UV varnish, followed by subsequent applications of gloss UV varnish to achieve the desired effect.
• ·   Ensure suitable inks are used prior to varnishing and that the inks are completely dry before varnish application.
• ·   Not recommended for paper weights. Consider a clear hot foil as an alternative.

Screen printing

• ·   All finishes can be successfully screen printed.
• ·   Paper and board inks, vinyl inks and UV inks can be used.

Blind embossing

• ·   All finishes can be blind embossed.
• ·   For subsequent laser printing, we recommend a shallow embossing.
