Photoengraving is a process that uses a light-sensitive photoresist applied to the surface to be engraved to create a mask that shields some areas during a subsequent operation which etches, dissolves, or otherwise removes some or all of the material from the unshielded areas. Normally applied to metal, it can also be used on glass, plastic and other materials.

Briefly stated, the process of making halftones is as follows: The subject to be engraved is photographed through a halftone screen, so-called. This halftone screen is a glass plate ruled with lines at right angles ranging, for different purposes, from 60 to lines to the inch.

This screen is placed between the lens and the sensitized plate. Screen printing can make sure that everything – from branded logos to warning labels – stands out.

Set the output to ppi and the method to ‘Halftone Screen’ (see fig.8). Set the half tone settings to ‘Frequency 45’, ‘Angle 45’ and ‘Shape Ellipse’ fig.9)(see. Now that your image is a half tone you are almost complete. But before we print and sand blast we must ‘Invert’ the image to create a negative.

This important measurement related to the way printers reproduce photographic images also defines the necessary resolution of an image. The LPI is dependent on the output device and the type of paper.

The screen ruling (lpi) is the number of dpi used to produce the halftone image and the resolutions used will determine the screen rulings that can be produced. Course screen rulings tend to be used in low quality reproductions, e.g.

newspapers, and fine screen rulings for high quality reproductions, e.g. fashion magazines or art prints (Kinyo. Halftone dots are referred to by a number based on the number of dots per linear inch.

This number is called the “frequency” or “Lines-per-inch – LPI.” Yes, lines-per-inch doesn’t seem right but in the old camera days you would refer to the halftone screen “ruling” and this is where it came from. Don’t Confuse DPI and LPI.

By allowing gray levels in images to be represented by varying the sizes of black dots, they made photographic printing on industrial scales, such as newspapers, practical.

You can experiment with the size and angle of the half-tone screen.

With 36 companies, this industry employs approximately people in the United States. Halftone is the reprographic technique that simulates continuous-tone imagery through the use of dots, varying either in size or in spacing, thus generating a gradient-like effect.

" Halftone" can also be used to refer specifically to the image that is produced by this process. Where continuous-tone imagery contains an infinite range of colors or greys, the halftone process reduces visual.The metal plates are to be purchased ready for use, coated with a thin gelatino-bromide emulsion like ordinary dry plates, and are placed in the dark slide (behind the ruled screen if for half-tone work).

After exposure the plate is developed in the dark room for 2\ minutes with a glycin developer, rinsed under the tap, and then immersed in a 5.Photoengraving, any of several processes for producing printing plates by photographic means.

In general, a plate coated with a photosensitive substance is exposed to an image, usually on film; the plate is then treated in various ways, depending upon whether it is to be used in a relief.
