Defects that occur in the fabric during the operation of printing are called printing defects. Each printing method has its own unique printing limitations and problems, which appear in some cases as printing defects. The appearance and magnitude of these defects are dependent on the printing paste, the printing parameters, and the printed patterns. Defects can be so small that they have no effect on the function of the patterns.

The causes and remedies of these common printing defects in the fabric are enlisted below:

1. Flushing / Wicking: Caused due to the Low viscosity of the print paste.
2. Bleeding: Bleeding defects occur in the fabric when printing paste that has already been applied bleeds into a subsequent paste or coating that is applied.
3. Misfits: A misfit is a print defect caused by improper alignment of the screens. Also known as out of the registration, misfits leave unprinted areas in the design.
4. Stick-ins: A stick-in occurs when a small fiber or piece of lint gets stuck in the screen opening.
5. Double printing: A double printing defect occurs in the fabric when the design to be printed is not in the correct position where it should be.
6. Scrimps: A scrimp defect occurs when the fabric creases underneath one of the screens during the printing process.
7. Pattern bending: The defect was created by the print head’s movement over the substrate.
8. Unwanted pigment marking on fabric: Because the screen has holes in it that should have been covered. This could be because of the aging of the screen and eventual damage or just improper exposure to light.
9. Mottled: Color applied unevenly during printing.
10. Crack or Miss Alignment in transfer printed fabric: Incomplete transfer of design from paper to fabric on transfer printing due to removal of transfer of paper while the fabric was still hot.
11. Doctor mark/streak: Doctor Mark defect occurs in the fabric when parallel lines appear on the fabric, vertical to the print on the fabric. It is called so because it is caused by a damaged or improperly set doctor blade in the printing machine.

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

12. Printing machine stop: As a result of the printing machine stopping the dye sometimes is smudged along the width of the fabric.
13. Color out: The result of color running low in the reservoir on the printing machine.
14. Uneven printing: Uneven printing defects occur in the fabric when the tone of the color of the 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

15. 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
