Printing Proofer


High quality proofs using gravure, gravure-offset or flexo inks are produced instantly using the K Printing Proofer. Featuring electronically engraved printing plates and variable printing speeds of up to 40m/min, this is an essential tool for all those involved in the manufacturing or use of liquid inks. Ideal for R&D and computer colour matching data, quality control and presentation samples. The K Printing Proofer is very easy to clean and all parts are solvent resistant.

Almost any flexible substrate can be printed or laminated
Excellent printability ensured by micrometer control
Multiple ink samples may be printed simultaneously
for comparison purposes
High printing speeds enable use of inks nearing press viscosity
Easy to operate with a footprint of just 400 x 500mm

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 via micrometers allowing repeatable settings for future tests.

Using the flexo head, ink is transferred from the printing plate to a plain stereo roller and then onto the substrate. Adjustments are again made by micrometers. Plain or step wedge plates are available corresponding to the various densities required for flexo printing.

The flexo head is employed and fitted with a plain rubber roller to transfer ink from the plate to the substrate. A machine supplied with the flexo head can therefore be used for both techniques with the possible addition of an alternative stereo/offset roller and printing plate if required.

Both wet and dry laminated samples can be produced on the machine using the gravure head with K-Lam laminating accessories. This includes
a rubber covered bed using a K-Lam bar to apply adhesive. Adhesive is applied in front of the bar and the machine then coats and laminates in one operation.
Dry laminating is carried out in two phases. The adhesive is coated onto one substrate and after evaporation of the solvent, the second substrate is subsequently laminated to it

The essential job of cleaning various machine components following each proofing run has been simplified by careful design. The illustration (left) shows the machine fitted with a gravure head pivoted back to the cleaning position. It can be seen that the printing plate, rollers and doctor blade are all exposed and easily accessible.

Printing plates for use with the Printing Proofer are electronically engraved 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.
