Screen printing on envelopes is tricky because the seam where the flap folds creates uneven thickness. The squeegee skips or deposits extra ink at the seam line. For clean results, print the flat sheet before folding if possible. If printing on pre-made envelopes, reduce squeegee pressure slightly over the seam area and accept that seam-area registration may be less precise.

Keep boxed and sealed in a dry environment. Don't unbox more than you need for a job. Kraft envelopes are more humidity-resistant than white wove. In monsoon months, store with desiccant packs if your workspace isn't climate-controlled.

Film positive production for screen making. Every screen starts with a film positive, and the quality of that positive determines the quality of your stencil. Tracing paper for hand-drawn art, layout work, and colour separation registration checks.

For film positives, print your artwork on OHP sheet using a laser printer or inkjet with pigment-based ink. What matters most is maximum opacity in the black areas. UV light must be completely blocked where you want your stencil to remain. Pigment-based inkjet ink on matte OHP film gives the densest blacks. Laser toner on polyester laser film is the other option. Use DTP Toner Darker spray to boost opacity if needed.

Store flat in original packaging away from light and humidity. OHP sheets are plastic and dimensionally stable, but they pick up static charge that attracts dust. Fingerprints and dust on your positive transfer as imperfections in your stencil.

Product labels, shipping labels, price stickers, bumper stickers, promotional stickers, asset tags, barcode labels. Paper-backed for indoor and short-term use. PVC-backed for outdoor durability, rain, sun, and handling resistance. The 20x30" format lets you gang multiple sticker designs on one sheet and cut after printing.

Print on gummed sheets the same way you'd print on flat card stock. The substrate sits on the press and the adhesive side faces down on the release liner. For screen printing, use inks appropriate to the face material. Paper inks for paper-backed, vinyl inks for PVC-backed. After printing and drying, die-cut or trim to final size. Be careful with blade depth. Set it to cut the face material and adhesive without slicing through the liner.

Store flat, cool, and dry. The adhesive ages, so sheets stored longer than 12 months may have reduced tack. PVC-backed sheets are more storage-stable than paper-backed. Keep sealed in original packaging to protect from dust and humidity. Adhesive that's absorbed moisture doesn't stick properly.
