Tracing Paper - Printing Notices

Printing Notices

• Offset printing:
  • Print multicolored files on a multicolored machine – this helps to avoid registration problems.
  • Packaging has to be removed immediately before printing.
  • Paper stacks should be fanned out.
  • Printing sheets should preferably be finished long grain.
  • Translucent paper is printable with all popular as well as very fine screen widths.
  • The use of frequency adjusted screen processes is also possible (FM-screening).
  • The fountain solution pH has to be controlled (pH greater than 5.5).
  • Only oxidative drying or UV-curing inks should be used.
  • Addition of drying material should be avoided.
  • Do not dry with hot air or infrared-heater, flatness problems may occur.
  • Use powder spraying sparingly.
  • Do not allow the stack after printing to be too high, thus allowing air to circulate to aid drying.
  • Transparent papers require longer drying times, this has to be considered.
  • Further processing can be done once the printing colors are completely dry.
• Inkjet printing:
  • Line and script printing shows good results.
  • Ink absorption is limited due to the high density of the transparent papers.
  • Longer drying times have to be considered.
  • Recommend a test-print.
• Laser printing:
  • Transparent paper offers a fine closed surface that provides a high image quality.
  • Due to high processing temperatures the paper may show some shrinkage or stretching effects.
  • Therefore it is essential to test the run ability of the paper with the precise printing conditions.
• Recommendation:
  • Transparent papers require a very high degree of mechanical treatment of the fiber.
  • Thus it is sensitive to temperature and moisture fluctuations.
  • The transparent paper should be stored in its original packing for 24 hours in the printing room.
  • Ideal climate conditions for the transparent paper are 18 - 23°C at 45 – 55 %RH air humidity.
  • Printed and unprinted transparent paper should be protected from moisture during storage.
