Fotospeed Lith developer is supplied as 2x 500ml liquid concentrate. Lith printing, using selected B&W papers, offers the printmaker unusual and unique effects unlike the results achieved by toning. This is a creative tool that does not require a lith negative. The color of the finished image is largely determined by a combination of the printing paper, the length of the exposure and the developing time. Rarely is a print left in the developer for the full processing time. The color of the image is captured by pulling the print as soon as the desired color is visible in the tray, anything from a subtle peach color, through a greenish brown to a cold black. Success with this process is very dependant on the printmaker's tenacity and experience gained only through trial and error. The instructions that accompany the Lith developer are very detailed and encourage experimentation. *Recommended Dilution for Lith Printing 1:12 or greater. *Recommended Dilution for processing Litho Film 1:3 as directed on box.
