+Where to find AkeBoose chamber identification number?

The "commission number” is the AkeBoose drawing number and it is unique for every chamber system manufactured. Knowing the commission number enables AkeBoose to find out all technical data about a specific chamber system.

The commission number is a numerical or alpha-numerical code, either:

- "99” followed by 4 digits.

- "AB” followed by 4 digits.

The commission number can be found in either of the following 2 positions on the chamber and suspension unit (please see image below).     


Please note that the illustration above is a depiction of our chamber system model ”Classic”, but the principle of the location of the commission number is the same in all our chamber system models.

+Replacing Strip-Blade holders in CLASSIC/FlexoCompact chamber

  1. When replacing damaged Strip-Blade holders, it is absolutely crucial that the new holders are mounted exactly in parallel. BEFORE the old holder is taken out of the chamber, the distance between the two Strip-Blade holders (old ones) must be measured in minimum three places (left, center, right) with a slide caliper.
  2. After this, ONE of the old Strip-Blade holders is taken out and replaced by a new one. The new holder is positioned so that the distance (left, center, right) is identical to the old measurements.
  3. Finally, the next Strip-Blade holder can be exchanged and once again installed in parallel with the already installed new strip-blade holder (left, center, right).

By replacing one Strip-Blade holder at a time, you will keep the original position and ensure perfect alignment, including the overall function of the chamber. 

+Possible causes for scumming/hazing in gravure printing

Scumming, or hazing problems, occurs when the doctor blade does not wipe away the ink correctly on non-printing areas. The result in print is a light tone on areas which should not have any tone on the printed substrate.

Possible causes

  1. Surface roughness of gravure cylinder too high.
  2. Doctor blade tip too thick.
  3. Doctor blade angle too shallow/low.
  4. Distance between doctor blade wiping position and the print nip too short.
  5. Ink dries too slowly.
  6. Poor ink quality.

Please note! There must always be a certain layer of ink after wiping; otherwise there might be an adhesive wear of the doctor blade.

+Advantages with thin and narrow doctor blades?

Thin and narrow doctor blades are the key to high quality printing, and a cost efficient alternative to lamella doctor blades in gravure printing.  The AkeBoose Doctoring Systems are using fitting holders, named Strip-Blade - and NewEdge holder, to be clamped, once and for all, into the machine holder, which makes blade changes very quick and easy.

Boths systems use 10 mm wide doctor blades with rounded edges, thickness 0,065 mm – 0,152 mm. Models for positive doctoring are also using a back-up blade (normally  8,5 x 0,152 mm). The return of investment for the doctoring systems is normally less than 6 months, due to lower prices on high quality doctor blades, compared to lamella blades.
