Graphica Pressboard

What substrates can we crease?

We can crease any substrate

  • Paper
  • Folding Box Board
  • Corrugated
  • Litho Laminated

Features:

  1.  Used more than 77 countries worldwide. World’s most advanced creasing matrix made from plastic, pressboard and pink fiber and resin for various die cutting jobs.
  2. Accurate locator – ensures perfect registration
  3. Low profile chamfer – board flows freely over the matrix; board marking is reduced
  4. Finger lift adhesive tape – backing paper easily and quickly removed
  5. New and strong adhesive removes cleanly from the plate after use, will not move about during die cutting jobs
  6. Special sizes available to suit all board types, off-centers and multi-crease for close creasing rule
  7. It is extremely durable and accurate and provides benefits in time and cost.

Operation Procedure

  1. Measure the length of the creasing rule
  2. Mark the measurement and cut the matrix
  3. Mount the cutting piece into the creasing rule with locator
  4. Remove all of the backing tapes
  5.  Transfer the matrix to the die cutting steel plate
  6. Remove all of the locators
  7.  Miter the sharp angle

23.50 23.40 23.30 23.20 23.10 23.00
200 0.28mm 0.3×1.0 0.4×1.0
250 0.35mm 0.3×1.2 0.4×1.2 0.5×1.2
300 0.42mm 0.3×1.3 0.4×1.3 0.5×1.4
350 0.50mm 0.4×1.4 0.5×1.5 0.6×1.5
400 0.56mm 0.5×1.6 0.6×1.6
450 0.63mm 0.5×1.7 0.6×1.7 0.7×1.7
500 0.70mm 0.7×1.7 0.8×1.7
Notes: the specifications above are only recommendation, among which the specifications marked withare recommended to choose firstly.

For instance: the thickness of the cardboard: 0.52mm; the thickness of creasing rules: 0.71mm, according to calculation formula: A=0.52≈0.5(mm); B=0.52 x 1.5 +0.71 = 1.49 ≈1.5(mm),so we should choose the size of 0.5 x 1.5.
