Digital printing fabric

 DIGITAL  AOP:

1.       Screen is not necessary for this printing.

2.  Digital design development process is different as:

     a) Photoshop software is used here for most of the design. Sometimes Adobe Illustrator software is also used.

     b) Color separation is not necessary. The work needs to do on the main image or the file of the design.

        c) The brightness/contrast of the design file needs to increase or decrease for color matching of the main sample. Example: The color contrast-which is used for woven fabrics is not the same for knitted fabrics. Another type of color contrast is used for knitted fabric.

       d) Decision can be made depending on the texture of the design that which mode should be used in developing design RGB mode or CMYK mode.

     e) Maximum designs are used 8 inks in the printing on fabrics. They are: A) Cyan B) Magenta C) Red D) Yellow E) Black F) Orange G) Blue H) Grey.

3. Blended fabric like PC, and CVC is not possible to print.                          

4. The quality of digital printing on deep-colored fabrics is not good enough.

5. White color print is not possible.

6. Reactive, Acid, Disperse and pigment can be done by digital printing.

7. Singeing and mercerization of fabric are very important for a high-quality print effect.

8. To develop a design RGB and CMYK both modes are possible. To get a better quality of printing the file of the design printing needs to be cleared.

9. The resolution has to be 300-1200 pixels per inch when developing the design. The resolution is selected depends on the quality of the print. For higher resolution, it takes higher time in developing design, the production is slowed down and a better quality of printing can be achieved.

10. In digital printing, the buyer provides the artwork and the color is matched by following the artwork.

11. The production rate is lower. The production depends on the machine head. The higher the number of heads, the higher the production. Generally, the production rate is (1-3) m/min. The production rate of the MS Lario machine is around  140 m/min. Only Robin Tex has the machine.

12. The printing needs to do in an Air-Conditioned room. Where the temperature of 25°C and Relative Humidity (RH) of 65%±2% is required. Otherwise, it will affect print heads and color continuity.

13. The pretreatment process is also needed here before printing. But here needs less chemical than traditional printing for coating. Thickener, Urea, Sodium Bicarbonate, and water are needed for coating. Sometimes resist salts are also used depending on the types of thickener.

14. Fabric printing is done through head up-down.

15. Uses of water is 90% less and electricity is 30% less.

16. Natural thickener is more suitable for color continuity.

17. There is no limitation on color. As a result, better sharpness can be attained.

18. Steaming is required after printing. Fixation is done in steaming.

19. The printing speed is not high.   

20. Accuracy of color is very difficult to maintain.
