Belt Oven

The tool used to cure a t-shirt. It comprises of several infrared heat panels that are tasked with heating the ink up to 330 degrees Fahrenheit.

Bleeding

This happens when the printed ink migrates outside your printing area and into the surrounding areas of your shirt. This can happen with two different colors printing closely as well.

Block Out

An emulsion like chemical that’s not usually light sensitive. It’s usually used to fill all the unwanted openings in the stencil on your screen after the exposure and washout processes.

Butt, Butt Registration

A scenario where the edges of two printed colors (that are different) come edge to edge but don’t overlap.

Capillary Films

Pre-sensitized emulsion on the film base that comes in rolls and sheets. This is used in the place of direct liquid photo emulsion.

Catalyst

A substance that modifies and raises the rate of a given reaction without being used up in the process. The substance is usually used in smaller quantities.

Choke

A sort of trap for reducing the size of first color printed slightly. It covers this color with another color with the aim of trapping the underlying color with the overlapping top edge color.

Color Composite

Full color rendition of your artwork exactly the way you intend it to appear on your tee.

Continuous Tones

Refers to the tonal ranges similar to those used in photographs. The tones are rendered in continuous shadings in full colors.

Coverage

Describes the quality or amount of ink laid down onto a tee when screen printed. Alternatively referred to as opacity.

Crest

A design that has been printed over the heart region of a t-shirt.

Cristalina

Degrease

Removing all traces of oil, grease, soil, and other foreign matter etc- usually by treating with a chemical.

Drying Cabinet

The place where a freshly emulsion coated screen is dried. It can be self-contained and light safe with fans or vents that facilitate air circulation for faster drying of the emulsion.

Durometer

One of the few measures of the hardness of a material.

Emulsion

A light sensitive liquid chemical applied to the screen.

Emulsion remover

The process that involves using a reclaimer or stencil remover needed to remove an emulsion when you want to reuse your screen for another task.

Exposure Latitude

The range of exposure duration that will create a usable stencil during the screen exposure process.

Extenders

Chemical additives found in the plastisol ink, and play a crucial role to smooth the texture, reduce opacity, and increase volume, without interfering with the viscosity.

Fibrillation

Occurs when you wash a printed tee and the underlying fibers come through the print. They look fuzzy and make your print look like it’s faded.

Flash Cure

The process of exposing your printed garment to heat source less than that associated with curing oven so as to make the ink dry to touch.
