What is Printing?

The application of color in a predetermined pattern (design) on the fabric's surface using various techniques and methods is called printing.

What are Printing Defects?

Defects that occur in the fabric during the operation of printing are called printing defects. Printing defects may occur due to many reasons such as the following:

  • The printing procedure did not take place properly
  • The fabric was not prepared properly before printing
  • The fabric had defects prior to printing

Types of Printing Defects

Some of the types of printing defects are as follows which will be discussed in detail later:

  1. Bleeding
  2. Splashes of Color Paste
  3. Cracking
  4. Doctor Mark
  5. Double Printing
  6. Pattern Bending
  7. Frame Marks
  8. Speck
  9. Uneven Printing
  10. Creasing
  11. Unprinted Area

Bleeding

Bleeding defect occurs in the fabric when the color on design on the fabric runs out as a result of which the design outlines becomes unclear. The causes for this type of defect can be as follows -

  • The print paste has low viscosity
  • The concentration of the dyestuff in the print paste is too high

Splashes of Color Paste

Splashes defect occurs in the fabric when the stains are made by the dyestuff of the paste. The causes for this type of defect can be as follows -

  • The speed of the machine was too fast due to which the dyestuff was not given much time to settle on the fabric
  • The print paste has low viscosity

Cracking

Cracking defect occurs in the fabric when the print paste starts to crack. The cause for this type of defect can be as follows -

  • The print paste viscosity was inappropriate

Cracking

Doctor Mark

Doctor mark defect occurs in the fabric when parallel lines appear on the fabric, vertical to the print on the fabric. The causes for this type of defect can be as follows -

  • The print paste has low viscosity
  • The concentration of the dyestuff in the print paste is too high

Double Printing

Double Printing defect occurs in the fabric when the design to be printed are not in the correct position of where they should be. The causes for this type of defect can be as follows -

  • The design was not correct
  • The print design was not able to adhere to the fabric

Pattern Bending

Pattern bending defect occurs in the fabric when the designs on the fabric are not aligned to the pattern that was intended to be printed. The cause for this type of defect can be as follows -

  • The cloth on which the design was to be printed was not delivered in the machine in a straight direction

Frame Marks

Frame Marks defect occurs in the fabric when the frame used to print on the fabric leaves a mark on the print. The cause for this type of defect can be as follows -

  • The frame was not installed properly in the machine

Speck

Speck defect occurs in the fabric when colored stains appear on the design of the print. The cause for this type of defect can be as follows -

  • There were undissolved impurities in the dyestuff that was made for printing which adhere to the fabric during the process

Uneven Printing

Uneven Printing defect occurs in the fabric when the tone of the color of design has gaps through the fabric. The causes for this type of defect can be as follows -

  • The screen was not prepared properly
  • The squeegee was used with uneven pressure

Creasing

Creasing defect is when due to a crease in the fabric, uneven printing occurs.

Unprinted Area

Unprinted area defect occurs in the fabric when some part of the fabric is not printed at all. The causes for this type of defect can be as follows -

  • The screen used for printing has foreign material stuck on it
  • The fabric is not able to take on the print paste properly due to foreign material on the surface
