Abstract

The current research and (The visual effectiveness of the techniques of the graphic display) (Experimental study), in four chapters, the first chapter dealt with the problem of research, which ended with the following questions:1. Do all the graphics techniques achieve equal visual efficiency at the field level?2. Does multitasking in the technical input of a single object provide greater efficiency for the optical field?3 - What are the graphics techniques that achieve high visual efficiency from other technologies?Then the importance of research and the need for it, and the goal of research in the recognition of the visual effectiveness of the techniques of the graphic, and identify some of the terms contained in the title of the research.The second chapter, entitled Mechanisms of the visual system in the applications of graphic techniques, in which the researcher talked about the mechanisms of the performance of the techniques of the manifestation of the graphic in terms of printing prominent, deep and window. The third chapter came as a procedure for the current research, through which the research society and its sample were determined, which included five works of graphics that were completed by the researcher with different presentation techniques as appropriate to the current research objective.The fourth chapter includes the findings of the researcher, including:)A) The effectiveness of the technique of clipping, as in the sample (1): 1- The texture: It has great effectiveness in showing the sense of texture of printed clips2- Color: It is very inefficient in their color entries (chromatic asceticism), because of the difficulty of impregnation of the parts.3-Line: It has a great visual effectiveness in showing lines4-Point: Few effective in showing the point configurations.5-Gradients: color gradients can not be produced according to this technique (low efficiency).6-Relatives: It has great visual efficiency in showing the protrusions on the surface of the printing paper, as does the blind printing technique.7-Number of editions: The number of editions is limited in this technique because parts of the scraps are damaged at each print process (actual few).8-Cost: Low cost.9-Availability of materials: Available widely.10- speed of completion: fast completion (high efficiency).11-The possibility of use color: can not use any type of colors other than ink (low efficiency).12-Size: Size is limited to the size of the Litho pressThe research findings:Each technique has its own efficiency, which differs little or much from other techniques.(B) The visual efficiency of the single karafic achievement increases with the increase in the working techniques.Then the suggestions and recommendations followed by the list of forms, sources and references that the researcher used to show the search as the current.
