Rives papers, text and boards give excellent printing results with all major print processes. To optimise the 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%.

Offset litho printing

For optimum results on textured products increase the blanket pressure or use a softer blanket to achieve consistent ink lay down.

Printing inks

• ·   Conventional positive drying inks should be used with or without infra-red drying assistance.
• ·   Fully oxidizing inks or UV inks may also be used.
• ·   Avoid using overnight / stay fresh / duct stable inks (this is essential for Ice White, where fully-oxidizing inks are recommended).
• ·   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.

Silk screen printing

• ·   Paper and board inks can be used, but when ink opacity is necessary vinyl inks give good results.
• ·   UV inks can be used.
• ·   For accurate ink placement the screen requires intimate contact with the substrate. Consequently some image detail will be compromised when silk screen printing on to the Rives textured papers.
• ·   It may be necessary to remove the paper texture from the image area to improve print clarity.
