Danger Warning for Machine Operation 

Settings, color and thinner adiition, as well as any working in the tampon free 

space may only be carried out when the machine is at rest. 

Hazardous Materials 

(Colors, Lacquers, Solvents, Leveling Agents, etc.) 

While handling hazardous materials to be used(colors, detergents, additives), the 

information of each respective safety data sheets must be paid attention to. 

Standard Tampon 

There is no risk of injury for the fingers while using standard tampons (tampon 

strength ≥ 35 to 40 mm) if used as intended. 

While using special tampons, tampon assembly, etc. additional protective measures 

must be carried out if required; i.e. two-hand switch, light barrier, loading and unloading 

equipment. 

Printing matter intake 

Printing Matter 

According to the kind / shape of the printing matter / printing matter intake, the risk of 

injury (jamming risk) between the printing matter / printing matter intake and the extending 

sword of the tampon cleaning changes. 

Additional protective measures must be carried out if required; i.e. two-hand switch, 

light barrier, loading and unloading equipment. 

Before casing sheets are taken off, the machine must be shut off and detached from 

the electricity network!

Oil feed regulator screw: Dose 5 drops per month. 

Oil: Hydraulic oil acc. to DIN 51 524 – HLP32 

Oil viscosity: 21-25 cSt bei 20°C. 

Too much oil leads to overoiling (slow cylinder).

LED (green) → lights up, when the power unit is ready for operation. 

The LED goes out, when the power unit function is impaired. 

Possible causes are: - There is no primary voltage at the power unit input 

- The secondary load is too high and the power unit 

cuts off

Possible printing faults 

The pad can only yield as good a pattern as it has picked up. 

If faults occur, make the following checks first: 

• Is the plate saturated with ink? 

• Check the ink pick-up on the pad (with mirror). 

Fault Cause Remedy 

Holes in print 

Splashes 

Clouds 

Distortion 

Too little ink = 

insufficient opacity 

Ink distribution nonuniform 

Contours not clear-cut 

• Air bubbles on ink pick-up. 

• Ink is too thin. 

• Pad is too flat. 

• Pad down-stroke too fast; hence too high a 

roll-over speed of pad print surface. 

• If the pad is splashed, this happens when the 

pad retracts from the plate. 

Reason: 

• Some of the deformation energy is 

converted to a static charging of the pad 

and the ink. 

• Occurs frequently in wide-area print zones 

(pad float), especially when printing non-flat 

surfaces; e.g. cylinders, cones. 

• Print surface has low points or high points, or 

is smaller than the pad area. 

• Print on non-plane surface is always 

distorted. 

• Ink too thick (viscosity). 

• Pad not yet activated. 

• Inadequate plate depth, or ink clotted. 

• Machine cycle time is too long or too 

irregular. 

• Pad retains too much ink. 

• Plate or film do not sound. 

Depth of etch irregular. 

• Plate part-clogged with ink. 

• Ink is crushed by the pad. 

• Pad stroke too short.. 

• Ink is too thick. (Saturation fault). 

• Too little ink. 

• Ink is too thin. Ink is crushed. 

• Cycle time is too long or too irregular. 

• Pad stroke too short. 

• Retarder used. 

• Possibily too great an etching depth 

> 30 microns. 

30 

• Adjust for thicker ink. 

• Take steeper pad. 

• Reduce speed of pad down-stroke. 

• Check the pad after ink take-up (mirror). 

• Adjust for thinner ink. 

• Use a softer pad. 

• Fit an ionizing rod in front of the plate. 

• Fill the low points, expand the pad roll 

surface. 

• Special measures are necessary. 

• Fill the low points, expand the pad roll 

surface. 

• Special measures are necessary. 

• Thin the ink. 

• Activate pad with thinner. 

• Check the plate and clean if necessary. 

• Reduce machine cycle time. Work with 

automatic control. Check work bench layout. 

• Blow cold air on pad, or prolong time 

between ink take-up and deposit. 

(Do not use retarder). 

• Check the film. 

• Clean the plate. 

• Set for thicker ink. 

• Correct pad stroke. 

• Check saturation. 

• Top up with ink; mix well. 

• Set for thicker ink. 

• Keep to cycle time. 

• Correct pad stroke. 

• Work without retarder. 

• New plate. Etching depth for steel plate: 

Normal 22 microns, for fine marks 16 

microns. 

• Use plastic screen film E 7812.
