Printability tester for gravure prints of 65 mm width.
G1-7: printability tester for gravure prints.
Dedicated tester to produce colour prints of conventional and UV gravure inks.
Available with print width of 65 mm.
•Simple to operate
World-wide the best printability tester for gravure inks.
For gravure inks IGT Testing Systems markets the G1-7 printability testers for various printing widths.
These testers print colour strips with gravure inks 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.
The G1-7 printability testers produce colour strips which are suitable for many purposes, such as:
•Measuring colour with colour measuring systems/spectrophotometers, colour matching systems
•Density measurements, including establishing colour and density tolerances and determination of coverage, wear resistance, scratch resistance, flexibility, adhesion and gloss, ink transfer, light fastness and resistance to chemicals
•Testing printing quality
The G1-7 testers print on many sorts of coated and uncoated materials: paper, board, plastic film, cellophane, laminate, etc.
The G1-7 is used in the following industries:
•printing ink, paper and board, printing
•plastics, labels and packaging
•resins, lacquers and coatings
Simple to operate and of sturdy construction for intensive use over a long period; easy and quick to clean
Extensive processing possibilities for various substrates and gravure inks; substrate, ink and printing form simple and quick to change.
Excellent reproducibility, high degree of simulation of actual practice.
The G1-7 printability testers consist of an exchangeable engraved printing form which is inked with the aid of a doctor blade, and an impression cylinder. The substrate is attached to a carrier which is placed on the substrate guide, between the impression cylinder and the printing disc. The printing force is applied between the printing disc and the substrate, and at the same time contact is established between the doctor blade and the printing disc. With a pipette, a few drops of ink are applied to the nip between the doctor blade and the printing disc. The printing system is now started, the excess ink is wiped off and the image is printed. The doctor blade and the printing disc are now lifted automatically.
The substrate is removed for appraisal and the doctor blade and the printing disc are removed for cleaning. In gravure printing the print quality depends very much upon the speed, which is therefore adjustable in five steps.
Two revolutions of the gravure printing disc are automatically made; this fills the engraved cells better with ink. The second part of the total print is most suitable for further evaluation.
Makes prints of 65 mm width. Consists of a printing unit with an exchangeable engraved printing form, a doctor blade assembly and an impression cylinder. Printing speed and printing force are adjustable to get the printing results correlating with printing press.
There is also a gravure tester available with a printing width of 50 mm ; the IGT G1-5.
