Printing Tips

Printing on PolySyn™

Ink Selection

We recommend that you work with your current ink supplier to choose the ink that will provide the end result you are seeking. We have done our research with Superior Printing Ink and achieved excellent results. Standard paper inks can be used for one-color applications. Control of the ink-water ratio should be carefully monitored. Specially formulated inks are recommended for multi-color close register work. Provide your ink supplier with a sample of PolySyn™, and they will recommend the most suitable job.

Standard inks with high solvent content may cause distortion in print quality on close register multi-color work - especially on lightweight gauges. We suggest using special ink with a very small concentration of mineral oil on it. Drying by oxidation is also recommended. Inks are available in a great range of single color and in process sets with four (4) colors. State the name of the product when requesting special ink.

Offset and Letter Press

PolySyn™ is suitable for small offset presses and standard printing presses. We recommend a test before printing.

Usually, standard paper ink will work nicely.

To Avoid Set-off

When proofing, it is important to avoid using too much ink. This may cause set-off while in production. We recommend low ink film weight for a clearer image.

Drying

Drying time is 4 - 5 hours. PolySyn™ absorbs ink well whether it is applied directly from the can or thinned before applying. Consult with your ink manufacturer about drying times and using UV drying techniques for UV inks.

Excessive heat causes tension on the material. This could impair work on the web-fed multicolor presses.

Plates

We recommend metal plates rather than paper melinex plates. Fount additives might hinder or prevent drying when paper plates (with a grained surface) are used instead of anodized (metal).

Water and Ink Balance Prevents Dampening of Fountain Solutions

Dampening is a major hazard when litho printing. Using plain water with pH level of 6 or higher will accommodate fountain solutions. We recommend reducing the manufacturer's recommended ratio by 50%. Excess water or fountain solution could impair drying time.

Other Printing Techniques

Screen-printing: We recommend inks that are oxidized and that dry by evaporation for this printing technique. Consult with the ink manufacturer about the end application and test the ink before applying. If using an oven for drying, the temperature must not exceed 150° F (64° C), and a steady temperature should be maintained. Avoid overheating. Prints should be racked for drying.

Tags and Labels

Solvent and water-based inks work nicely for printing tags and labels on PolySyn™. We do not recommend heat fusion lasers or photocopying with PolySyn™. Cold or chemical fusion lasers and copiers are compatible.

Numerous Finishing Choices

PolySyn™ is conducive to; guillotining, binding, die cutting, folding, scoring, drilling, perforating, and more. The possibilities are endless, when left to your imagination!
