Digital Printing
Digital fabric printing is relatively new technology with tons of applications. It is described as any ink jet based method of printing colorants onto fabric.
Digital can print any design on all kind of fabric, like cotton, poly or silk etc.
Pre-Treatment for digital print
Before going to digital print all fabric need to coated with chemicals and prepared for digital printing.
Digital Printing Process
During the printing process, the fabric is fed through thr printer using feed roller and ink is applied to surface of fabric in the form of thousand tiny droplets.
fabric is printed by digital printers with the design prepared on computer using ink jet based method of printing colorants onto fabric.
The fabric is then passed through steam/heat chamber to cure the ink.
Then steamed fabric required washing and drying.

Cost for production
So for the print where we can’t achieve desired result on rotary printing machine we have option of going for sublimation print thru roller printing machine (true for only polyester fabric), but because of the cost of the roller sampling is problem (cost of one copper roll appx 50000 to 60000 rupees ),
We take the route of printing of paper by digital printing machine using low sublimation disperse dyes and transfer on to the fabric using hot paper press for sampling only.
The result of heat transfer printing and digital printing using low sublimation disperse dyes would be the same. Cost-sublimation/heat transfer in the bulk is cheaper than the normal rotary print but the quantity per print
should be more than 20000 meter otherwise the cost of printing will be high because of copper roll cost.
Advantage of Digital Printing
The image can be printed all over the entire item, with no difficulty in printing all the way to the edges.
Colors can be extraordinarily brilliant due to the bonding of the dye to the transparent fibers of the synthetic fabric.
It is time saving for sampling as compare to rotary process. Truly continuous tones can be achieved that are equivalent to
photographs, without the use special techniques such as half-screen printing.
Time saving for sampling only.

Disadvantage of Digital Printing
Back side of fabric always be white. Sampling and production cost is high. Cost and lead time will be high for bigger
run. Speed of digital printing is very slow.
