Causes and solutions for blurred prints, lines and texts.

Causes of Pad

• The pad may be too soft. In this case, a harder buffer should be used.
• The shape of the bumper may be wrong. In this case, different shaped bumpers should be tried.

Causes of Printing Block

• Incorrect raster may have been used in the cliché. In this case, the cliché should be tried again by applying a different raster.
• If the cliché is too deep, printing should be tried again with a new cliché with less depth.
• If the wrong type of cliché is used, a suitable type of cliché should be used, for example, a steel cliché should be tried instead of polymer.

Causes of Ink

• The ink may be too thick. In this case, the printing should be tried again by adding some more thinner.
• If the ink is too thin, the amount of thinner should be reduced and the printing should be tried again.
• In case the ink dries slowly, it should be tried by using a faster drying thinner or by reducing the printing speed.

Material-Related Causes

• The material surface may be dirty. In this case, the material must be pre-cleaned.
• The material surface can be rough or chipped. In this case, another type of material should be used. If not, a harder pad can be used.
• The material surface may be uneven. In this case, a specially shaped bumper and buffer connection should be used.
• In case of pressure too close to the material edge, the device should be prepared in such a way as to prevent the pad from slipping.

Other Reasons

• The printing elements may not be stable enough. High speeds cause the bumper to vibrate. The speed should be reduced. For this, a new mechanism has to be created. If necessary, it should be stopped for a while during printing before touching the material in order to prevent the pad from vibrating.
