F1 Flexo and Gravure Proofer – F1, F1 Basic, F1-UV, F1 Corrugated
A range of IGT Microprocessor controlled, dedicated flexo and gravure proofer. Large selection of anilox rollers for flexo printing and gravure printing. Repeatedly lays down consistent ink film thickness. Suitable for UV or solvent based flexo and gravure inks. Selection of models available including with an integral UV dryer unit and for corrugated board printing.
Specially designed for computerised colour measuring and colour matching systems, the F1 tester removes the need for colour matching tests on press. It is simple to operate, reliable and sturdily built for intensive use over a long period.
Applications:
The F1 tester colour strips can be used for a wide variety of purposes including testing print quality; use with spectrophotometers, colour measuring and matching systems; visual appraisal; density measurements including colour and density tolerances and determination of coverage; wear and scratch resistance; flexibility; adhesion; gloss; ink transfer; light fastness and resistance to chemicals.
The F1 tester is able to print on a variety of coated and uncoated materials including paper, board, plastic film, cellophane, laminate, labels and textiles. It is used regularly in the printing ink, paper and board, printing, plastics, packaging, corrugated board and labelling, resin, lacquer and coatings industries.
Features:
- For use with a variety of substrates and inks
- Substrate, ink, engraved roller and printing disc are simple and quick to change
- Print occurs after two anilox revolutions
- Printing disc can be inked up to 20 times before making the print
- Electronic printing force and speed control
- Excellent reproducibility
- Quick and easy to clean
For flexo printing directly onto fabricated corrugated board, a special smaller diameter printing form cylinder can be supplied, offering a wider printing nip and allowing board up to 4 mm thick to be printed.
Operation:
The F1 tester has an inking section with an engraved anilox roller and doctor blade, a printing section with a photopolymer printing form and an impression cylinder. Ink is applied to the nip between the doctor blade and the anilox roller. During print, the ink is transferred from the anilox disc to the printing form and then to the substrate. Doctor blade, anilox disc and impression cylinder are lifted automatically.
F1 Flexo and Gravure Proofer
Print speed, anilox and printing pressures are selectable. Two successive prints are made and the second is used, being the most consistent and produced from a pre-wetted disc.
In gravure mode, the print is made directly onto the substrate and mounted onto the printing disc cylinder.
