Direct textile printing plottors working process on fabric
Direct textile printing plottors are technical solutions that have only been introduced on the market in these two years.
The original idea was to use a plotter previously used to print the design onto sublimation paper (subsequently transferred to the fabric by a calender or flat press), using a new ink suitable for direct printing onto the fabric, combined with a heat source (eg oven/calender) Machine) to achieve sublimation without additional steps.
This idea became the reality of some manufacturers in the 1980s.
However, in practice, the use of fabric is very different from processing paper.
Plotter manufacturers quickly realized that they needed to manage the various stages in the production process:
*Processing fabric
*Loading cloth into the machine
*Pull it over
*Initial drying
*Adjust the passage of the fabric in the oven
The key stages of the traditional textile manufacturing industry are well known, but these are the problems of the “new” digital presses.
At first, plotter manufacturers encountered unpleasant surprises: they knew that the design of paper, PVC and vinyl printing machines was basically insufficient.
They quickly discovered that the nature of fabrics meant that they were in a constant "moving" state, unlike their familiar supports, so the fabric was difficult to control.
In terms of technology, the equipment you need is: a plotter for direct textile printing and an in-line/single oven or calender for fixing and developing dyes.
Unlike the transfer, the right side of the design is printed on the fabric because there is no mirror transfer.
The speed of the plotter with an online oven must be adjusted based on the length of time the fabric is left in the oven, and vice versa, to prevent excessive yellowing or shrinkage of the fabric.
As with printing on sublimation transfer paper, it is important to prevent the print head from touching the support.
One of the major challenges for engineers in direct textile printing is finding the best application and solution so that all fabrics have the same tension, preventing the print head from contacting the support during scanning along the width of the fabric.
In terms of materials, polyester fibers are the best choice, but specific chemicals need to be applied. This allows the ink droplets to stop without swelling, thus ensuring excellent design clarity. However, this means that fabrics treated in this manner are generally more expensive than fabrics used for transfer printing, but the additional cost is offset by paper cost savings.
Some special applications (such as flags) need to transfer the color to the opposite side of the fabric; since it is not possible to adjust the temperature and speed as with a calender/press, it is necessary to source the product or fabric to be processed on the market.
Using a direct-flow plotter can reduce the range of items that can be printed directly, such as felt, carpets, and carpets. Stretching an article requires the use of a permanent adhesive pad placed at the entrance of the machine to keep the fabric stationary, thereby preventing shrinkage, which would make it impossible to achieve proper printing.
