CG1
Printability tester to produce colour prints with conventional and UV offset inks and to cover with lacquer or varnish.
Description
IGT CG1: Printability tester to produce colour prints with conventional and UV offset inks and to cover with lacquer or varnish.
Dedicated tester to produce colour prints of conventional and UV offset inks. Besides making prints with offset inks the CG1 has additionally the possibility to lacquer an already printed strip with a lacquer of low viscosity. The lacquer is applied to an engraved printing form with the help of a doctoring system. With this tester the influence of the lacquer on the printed ink can be tested.
World-wide the best printability tester for offset inks.
IGT Testing Systems supplies the C1 type printability testers, which are simple but very successful all over the world for offset inks in various printing widths.
Makes colour strips with offset inks with a known ink layer thickness which can be used for many purposes. Specially designed for computerized colour measuring and colour matching systems.Saves costs because colour tests on the printing presses are no longer necessary.Can print directly on all substrates including ready tubes or cans, version CTx3 can do this on any diameter between 16 and 68 mm.
APPLICATIONS
The C1 printability testers produce colour strips which are suitable for many purposes, such as:
- Measuring colour with colour measuring systems/spectrophotometers e.g. in colour matching
- Visual appraisal
- Density measurements, including establishing colour and density tolerances and determination of coverage, wear resistance, scratch resistance, flexibility, adhesion and gloss, ink transfer (in g/m²), light fastness and resistance to chemicals.
- Testing printing quality, gloss, mottle and set-off.
The C1 tester prints all sorts of coated and uncoated materials like paper, board, plastic film, cellophane, laminate, metal, etc.
-
The C1 tester is used in the following industries:
- printing ink, paper and board, printers
- metal, plastics and packaging
- resins, lacquers and coatings
- raw materials
OPERATION
The C1 type printability testers consist of an inking section and a printing section with removable printing disc (printing form). The inking unit consists of two aluminium drums and a top roller.
The distribution of the ink only takes 30 s due to the diameter ratio and the drum movement. The inking time of the printing disc is 15 s.
Cleaning the systems is very simple and quick, due, among other things, to the fact that both aluminium drums are driven. The printing unit consists of the printing form and an impression cylinder. The substrate is attached to a substrate carrier. The substrate carrier with the substrate is then placed on the substrate guide, between the impression cylinder and the printing disc.
After the printing force has been applied, the print is made automatically. The printing disc is then lifted automatically, after which the substrate is removed for appraisal and the printing disc is cleaned. It is also possible to print on drink cans: for this purpose they are slid on the impression cylinder, the substrate carrier not being used in this case.
The printing force can be set in 19 steps between 100 and 1000 N.
For printing on drink cans, the impression cylinder can be replaced with one of a different diameter.
Features
Makes prints of 50 mm width. The lacquer is applied to an engraved printing form with the help of a doctoring system. With this tester the influence of the lacquer on the printed ink can be tested.
The inking unit consists of two driven aluminium drums and a rubber top roller. The distribution of the ink only takes about 30 seconds thanks to the diameter ratio and the oscillating drum movement. The inking time of the printing disc is about 15 seconds. The occillating drums makes cleaning fast and easy. Printing form is automatically brought under pressure, printed and lifted.
