CMYK Halftone Magic- A majority of screen print work is printed using inks mixed for a specific color. Qualities such as color and transparency are controlled on a per-batch method. The color in the bucket is what will print on the page. This is "spot color" Another prevalent color methodology is CMYK process color. CMYK is printed using Cyan, Magenta, Yellow and Black. (Black is noted as "Key" in CMYK.) The combination of these four colors along with the variable dot size of halftone, can replicate a wide color gamut. Interestingly, if only solid color inks are overprinted CMYK only yields seven colors. It's the halftone that provides the color range. Rather than being mixed in the bucket, the colors are mixed in your eye! From color laser printer pages to vehicle wraps, CMYK halftone printing is everywhere! Printmakers can lever CMYK technologies to get full color prints with minimum stock of ink colors. Nothing comes for free thoug...
The Exposure Table- At the heart of screen printing is the creation of the screen. One of the earlier techniques, drawing fluid and filler, featured artwork created directly on the surface of the screen . When the printing is complete, the artwork is removed from the screen and lost during screen reclamation. Exposing a master image to a photosensitive emulsion on a screen allows the reclamation of screens without loss of the artwork. Now the screens are simply tools of the craft rather than artwork originals. Exposure tables are a nice tool to have although screens can certainly be "burned" using halogen shop lights and a watch. Screens can even be exposed using the sun! At it's core, an exposure table consists of a bright, non-point light source and a way to hold the artwork master tightly to the emulsion on the screen. A tight fit reduces light bleed and allows detail to be transferred to the emulsion. Several types of masters can ...
My first CMYK print. A combination of hand drawing and scanned images prepared for four color process printing. Of all the printing tricks and techniques CMYK prints are the most fun.
