The family of TESA® Softprint foams in its two standard thicknesses of 0.38 and 0.50 offer a high quality of printing, constant and long productions in flexography. For typography equipment and some flexography machines, mounting tape for plates are available in the thickness range 0.10 to 0.38 mm. We have stock in large reel and our own cutting service to ensure an agile and precise service to our clients. We have other special tapes for use in continuous printing processes such as splicing tape, grip tape, plate edge, etc.
Although there are other variables, such as doctor blades or anilox, that can affect the printing process, in the current flexographic industry, foam plays an important role that goes beyond fixing the photopolymer plate.
We can choose the strength of the adhesive by placing a greater tack on the face of the union to the cylinder printing and a softer adhesive on the face of the cliché. In this way, we can easily reposition the cliché during the positioning process and it will be easier to remove it once finished production, being able to reuse the foam for several different jobs. Stronger adhesives are available when working with plates thicker than 1.14 or small diameter developments to ensure bonding at the joints. The adhesive on the faces leaves no residue when removed.
Yes, there is a TESA sofprint in purple, with an intermediate hardness that allows 70 to 90% of the jobs to be carried out with good quality on a flexo printer. In the case of very large backgrounds or high-definition four-colour prints, it would be necessary to evaluate whether the quality is acceptable under the customer’s requirements.
Yes, TESA’s foam designs allow for the removal of the foam deformation plate and for the foam to maintain its performance so that it can be reused several times. This is a trend among more and more printers that improves productivity and lowers costs.
There are several solutions, such as using Tesa’s Softprint FLEX foam, or another reference that has better adhesion face to plate, applying an edge sealing tape or using the Magic CT marker when a sealing tape cannot be applied.
Yes, it is advisable to clean it so that there is no residue from inks, adhesive or the cleaners used in the process, as this can create gluing interference and lead to the cliché coming off or making it very difficult to remove the cliché at the end of the job.
