PRINTING PLATES

The GP100 uses the same electronically engraved printing

plates as used on our well known Printing Proofer and are

manufactured in exactly the same way as production cylinders.

A choice of one or more of the standard plates available will

normally be satisfactory but special plates including those with a

logo and/or company details can be supplied. Maximum engraved

area: 160 x 95mm.

GRAVURE

Ink is transferred from an electronically engraved printing plate directly onto the substrate, which is attached to the rubber impression roller. Doctor blade and roller adjustments are made pneumatically allowing repeatable settings for future tests.

CLEANING

The essential job of cleaning various machine components following each proofing run has been simplified by careful design. The illustration (below) shows the doctor blade being removed for cleaning. It can be seen that the printing plate and impression roll are easily accessible for cleaning.
