IGT C1 Offset and Letterpress Proofer Series – C1, C1-5, C1-7, CX3, CX4

A range of seven IGT offset and letterpress ink proofers for producing consistent ink film thickness repeatedly. Has a built in inking unit, selectable printing pressure and speed. Ideal for quality control of offset printing (conventional or UV) and letterpress inks. 15, 20, 35, 50 or 70mm wide print areas.

The C1 range of printability testers consists of 7 models, an efficient and reliable way of making colour strips with offset inks to a known ink layer thickness. The C1 Series consists of:

C1 for printing flat substrates with a print width of 35 mm. Tubes and cans with ID of 63-68mm can also be directly printed with the addition of an optional impression cylinder
C1-5 for printing flat substrates with a print width of 35 mm or 50mm. Tubes and cans with ID of 63-68mm can also be directly printed with the addition of an optional impression cylinder
C1-7 for printing flat substrates with a print width of 35 mm or 50mm or 70mm.  Tubes and cans with ID of 63-68mm can also be directly printed with the addition of an optional impression cylinder
Cx3 for printing flat substrates with 3 successive prints side by side, each with a print width of 15 mm. Tubes and cans with ID of 63-68mm can also be directly printed with the addition of an optional impression cylinder. Single prints of 20mm or 35mm can also be made.
Cx4 for printing flat substrates with 4 successive prints side by side, each with a print width of 15 mm. Tubes and cans with ID of  63-68mm can also be directly printed with the addition of an optional impression cylinder. Single prints of 20mm or 35mm  can also be made
C1-T specifically for printing a single 35 or 50 mm wide print directly onto a tube or can with ID of 16-68mm.
CTx3 specifically for printing either 3 x 15mm prints successively directly onto a tube or can with ID of 16-68mm or for printing a single print of 35 or 50mm wide on a tube or can

Play Video For IGT CI ProoferResults are consistent and reproducible and offer a potential cost saving because of the high degree of correlation with on-press results. Designed for intensive use over long periods, they are sturdily built, simple to operate and can print on a wide variety of coated and uncoated materials including paper, board, plastic film, cellophane, laminate and metal.

Applications:
The C1 range can be used:

  • for testing printing quality, gloss, mottle and set-off; visual appraisal; colour matching and measuring colour with colour measuring systems and spectrophotometers
  • for taking density measurements including colour and density tolerances, degree of coverage, wear resistance, scratch resistance, flexibility, adhesion and gloss, ink transfer (in g/m2), light fastness and resistance to chemicals
  • in the printing ink, paper and board, print, metal, plastics and packaging, resin, lacquer, coatings, cosmetics and electronics industries

IGT ink pipette applying ink

Features:

  • Simple operation – inking and printing in one instrument
  • Repeatable, reliable and reproducible results
  • Low cost
  • Lightweight
  • Easy to clean

Operation:

  • C1 printability testers consist of an inking section and a printing unit
  • The two driven aluminium drums and a removable rubber top roller evenly distribute the ink within
  • 30 seconds and the printing disc has an inking time of 15 seconds
  • The substrate is attached to a substrate carrier, which also acts as a printing disc mount during inking
  • The printing force can be set in 19 steps between 100 and 1000 N and the print is made automatically

Inking the printing disc

Technical data:

  • Inking section
    • Total inked area 720 cm2 Short cleaning time Aluminium drums, independently driven Special nickel-plated drums are available for UV applications which prevent dust collection from static
  • Printing section
    • Two types of rubber top rollers are available for conventionally dried and UV-cured inks Printing speed 0.3 m/s Printing force 100-1000 N
    • Independent drive Printing disc is automatically brought to pressure, printed and lifted; it can also be raised 4 mm to accommodate thicker substrates
    • Print directly onto beverage cans is possible via special impression cylinders of various diameters

  • Weight < 160 g for most of the available discs
  • Rubber, 65 Shore A, coated, for conventional inks
  • Rubber blanket, for conventional inks
  • Rubber, 65 Shore A, for UV-curing inks
  • Rubber blanket for UV-curing inks
  • Aluminium

Physical specifications:

  • C1 Accessory

    C1 with Top Roller and Printing Disc Accessory
    – also available with timer

    Weight 35 kg

  • Dimensions 650 x 400 x 300 mm (W x D x H)

Power requirements:

  • 115/230 V, 50/60 Hz

Option:

  • Forced oscillation of the aluminium inking drum, independent of the top roller to enable consistent ink film distribution of lower viscosity inks – can be retrofitted to some instruments.
  • The IGT ink pipette is recommended for applying ink to the top roller as this significantly increases the accuracy of the ink application.
