Screen Printing on Cylindrical Products

What To Expect When Screen Printing Your Cylindrical Products

Screen printing your cylindrical products is not as daunting as it seems. Going from 2D to 3D printing is effortless with the Model F1-DC. Whether your product is a shot glass or a growler, the process will be relatively the same. There are two methods for screen printing, one is gear driven and the other is friction driven. Both methods will provide you with indistinguishable printed results. The primary difference between both methods is the simplicity for operator changeover between products on the cylindrical screen printer. Gear driven tooling offers quick and simple changeover between products, while wareholder tooling requires more time for set up but it can accommodate a wide variety of different products.

Screen printing on cylindrical products requires you to think differently than you typically do with flat screen printing. For imaging your screen frame, you will need to make sure your desired image area does not exceed the circumference of the entire bottle. It is best to just think of the circumference as an axis for your print area for screen frame production. Cylindrical screen printing also relies on the screen frame moving back and forth rather than the screen saying stationary (with flat screen printing).

You may find that your products require an adhesion promoting processes. This is not always the case for solvent based inks but fairly common for UV inks. Flame treatment is typically all you need for adhesion promoting. UV inks cure almost instantly and requires a UV curing system to perform the chemical action of the ink being exposed to the UV wavelength. The SA flame treatment & UV systems provide the operator with universal tooling. You switch products without using adjusting tooling.

You may find yourself needing to print multicolor, which is not a problem with the SA cylindrical screen printing machines. Components for the screen printing systems are machined at high tolerances to ensure precise print repeatability. There are a few options for screen printing multicolor designs. The least expensive route is to simply use a mechanical pointer and align each product’s bottom identifier with the point, results of this method can be seen here. Your other two options are automatic mechanical registration or optical registration.
