10. Graphic Arts Film : Some kind of plastic substrate base film used in process work to make negatives or positives suitable for reproduction by a printing press. The emulsion coated on these films yield high contrast images suitable to process the plates or blocks for printing. They are also called litho film. Graphic arts films are available to suit for both black and white and colour separation work in the form of Panchromatic films. The films come as matt base and normal base. The matt base is suitable for Photopolymer plates for better contact. The matt films ensure better plate-film contact. The films are supplied by various photographic film manufacturers like Agfa-Gevaert, Ilford, Kodak, Fuji, Dupont, Indu (HPF), Konica etc. The graphic arts film comes in different thicknesses. Suitable films for halftone work, image setting and line work is available. Films suitable for use for processing the photopolymer plates are also available as they require high density.
11. Graphic Design: A graphic image is one that convey visual message of the product. The graphic design combines image and typography to convey the message. The designer combines typography and images to produce attractive design element to communicate the messages to an audience. The message may be only an Logo or a simple message in print. Graphic design is a creative process that combines art and technology to communicate ideas. In order to make the graphic design more effective the designer and the client will discuss what kind of message is to be conveyed and which way will be effective to reach the targeted audience. Type based designs are nothing but using words in an attractive way to convey a message instead of using pictures. A designer uses different typescripts, type size, colors, borders, shadings, columns, margins, spacing etc to make the text unique and attractive. When he combines both text and images to convey the message it should be creative and catchy respectively. A graphic designer is the real bridge between the client and the audience. His aim is to convey the message to the audience in an attractive way, which should have a good response as well. Through his work a graphical designer should be able to tempt the audience to buy the product for which the designing has been done. The images used for the graphic design may include drawn, painted, photographed or computer-generated ones. In short, graphic design is visual communication.
12. Gravure : One of the four major methods of printing . The printing by Gravure is done using metal cylinders etched with millions of tiny wells that hold thin ink. Gravure is a high quality process that is capable of producing printed images which have a continuous tone effect similar to the photographs. Unlike other processes wherein some form of image carrying plate or metal block is required , the gravure process utilizes a the metal printing copper cylinder itself onto which the image is etched. The printing impression is made by the transfer of ink from depressions (cells) of various sizes and depths that are etched onto the copper cylinder. The various sizes and depths of the depressions in lieu of the image create the different densities of the image to match the original. The areas of the cylinder that are not etched become the non-image areas.
Gravure though a direct printing method has the images depressed (sunken) , the reverse of the Letterpress printing technique . Though this process of printing is most ideal for weeklies and magazines which have large circulation, Gravure is used in many packaging applications, like cartons and pressure sensitive labels.

13. Gripper Edge : The front edge of the sheet which is held by grippers on a sheet fed press before impression takes place. The grippers hold the paper in tight position in the gripper edge to allow perfect register in the print station and release them only at the delivery station. Therefore the paper printed on the printing machines will have sufficient white margin or non print areas to enable the grippers hold the paper without affecting the print image.
14. Gutter Margin : Every printed book will have white space in each page, which is non printed areas around all the four sides. The inner white areas of the pages which goes in to the stitching/ sewing edge for finishing the book is called the gutter margin.
15. Glass line paper: A wood free pulp paper which will be transparent, glazed and polished on both sides.
Guillotine : Cutting machines meant to trim the books and paper to sizes. Both manually operated and automatic programmable guillotine machines are available in the market.
