The use of information processing systems to solve the problems of indus-try, engineering, business, science and government continues to grow at anever-accelerating rate. Digital computers have become indispensable wherethe volume and complexity of computations and the quantity of requireddata make any other system unfeasible. Automatic plotting devices areused in conjunction with digital computers where graphic or pictorial pres-entations of computer data are more meaningful and easier to use thanextensive alphabetic or numeric listings. They are indispensable when thevolume of graphic presentations makes it uneconomical or impossible toperform the task manually.

CalComp digital plotting systems provide an efficient, flexible means ofproducing highest quality drawn, scribed, optically exposed, cut for strip-ping, or COM graphic presentations of computer output data, withunvarying accuracy. There is no restriction on format, so that a pictorialrepresentation may include any desired combination of axes, lines, letters,and symbols, with unlimited choice of scale factors, letter and symbolsizes, and printing angles.

The function of a digital plotting system is to present digital computeroutput in graphic form. CalComp offers a wide variety of equipment toperform this function. This brochure includes pertinent points of consider-ation in the evaluation of plotting systems, and provides specificationon the equipments available from CalComp.
