5. Print Gravure is a printing technique that uses a cylinder as a reference print.
6. Fleksografi Print is a printing technique that uses a reference printing plate of rubber or photopolymer.
7. Continuous Tone is a tone image is composed of very fine money
8. Offset Print is a printing technique using a flat plate print reference sebgai
9. Duotone is a process of mixing two colors are generally composed of a mixture of black color and special color or process color
10. Digital Printing is a printing technology without going through the process but the process of making the reference directly from digital data.
11. Delta E is the total value of two jangkuan color difference in CIELAB
12. FM screening is a method of image reproduction Diman done with the same great point but the distance is different.
13. Color gamut is a color that is able to limit generated by an object
14. High key is the image that has high total distribution on the part highlightnya
15. Hue is the color itself, such as red, green, blue, cyan, magenta, yellow, etc.
16. Halftone is the tone of an image formed from the raster dots of various sizes to fit the tone that represents.
17. ICC profile is a data that contains the characteristics and information from an equipment (ICC profile is the result of calibration)
18. Moire is a pattern we do not want the printed images, resulting from different arrangements between two or more of a raster.
19. Low Keys is an image that has high total distribution in the shadow.
20. Lightness is the brightness value of a color
21. Metamerisme is an effect where the same two things seemed certain when illuminated by light but it looks different when illuminated by other light.
22. Progressive Proof is a print made using single-color offset printing and is commonly used as an actual proof before printing.
23. Rossate is the pattern formed when all four color halftone screens are placed together in each corner rasternya.
24. Screen Printing is a printing technique that uses a silk screen printing as a reference
25. Saturation is the intensity of a color / saturation color
26. Color is secondary subtractive color from the color additive that is made up of cyan, magenta, yellow formed from the offset, paint, photo etc.
27. Spot Color is a color special / special color is used because of the limited color process
28. Spectrophotometer is a tool to measure the light that dipantulkam / transmitted through the color spectrum and is used for the manufacture of printing profile, either offset or printing.
29. Screen Angle is the angle raster used in print reproduction
30. Web Offset printing machine is a type commonly used to print newspapers.

METAL CASTING PROCESS

Metal casting process is to form a metal object by pouring metal into a mold search. Prints can be made from sand, ceramic, or metal.

In choosing a casting technique we have to look at products like what we want to produce, how the workload, whether the product is a mass product, and consideration of the sale price. All that to ensure the effectiveness of the foundry that we make.

Sand mold has the advantage of a molding process is relatively easy and inexpensive, but it raises some risks such as entry of the grains of sand to the mixture of liquid steel, which would certainly cause a loss in terms of product properties. Another disadvantage of casting with sand mold (sand casting) is a molder that is disposable, so when you finish used to mengecor the mold must be destroyed, can not be reused. However this process is still relatively cheap considering the price of silica sand, as printed materials, not too high. Casting with sand molds also require a riser which is a provision for the molten metal during cooling. Riser will be discarded at the end of the process, it makes casting with sand molds to be less efficient because there should be metal is wasted.
Certainly not suitable sand molds used to create mass products very much because it can only be used once. Therefore, permanent mold is used which uses high temperature resistant metal (Heat Resisting metals) as a molder.

Casting with permanent mold can also be done while giving the load of molten metal so that this process is called printing-press process. Results of this press printing process has several advantages over casting with sand molds which have a density greater product and avoid the possibility of entry of impurities into the molten metal. Examples of casting products metal frames are printed using a piston motor vehicles, and front suspension fork for a motorcycle.

Another type is a precision casting foundry. The product has a very tight dimensional tolerances, smooth surfaces, and usually form a complex. This process requires a fairly high cost, limited to small objects, and high difficulty level. Examples of these are the lost wax casting precision casting (investment casting).
