| There are two distinct types of .EPs files, one of which is a vector based graphics file and can be opened and easily edited for type, color, etc. in Adobe Illustrator or PC vector based programs like Corel Draw. They can be CMYK color, or flat pantone color based. These files could be "placed' or "imported" into Pagemaker (or Word, Quark, etc.), but not opened by it. They can be almost infinitely scaled in size without degrading the output because they are vector based. The other is an .EPS photo file, flattened, set resolution "picture" type file. It can be opened in PhotoShop or other image editing programs, also placed or imported into Pagemaker (or Word, Quark, etc.), but it will be significantly degraded if scaled beyond the set resolution. These are usually CMYK files, or can be set as Pantone duo-tone, tri-tone files. |

| A halftone image is made up of a series of dots rather than a continuous tone. These dots can be different sizes, different colors, and sometimes even different shapes. Larger dots are used to represent darker, more dense areas of the image, while smaller dots are used for lighter areas |

| TIFF is a flexible, adaptable file format for handling images and data within a single file, by including the header tags (size, definition, image-data arrangement, applied image compression) defining the image's geometry. For example, a TIFF file can be a container holding compressed JPEG and RLE (run-length encoding) images. A TIFF file also can include a vector-based Clipping path (outlines, croppings, image frames). The ability to store image data in a lossless format makes a TIFF file a useful image archive, because, unlike standard JPEG files, a TIFF file using lossless compression (or none) may be edited and re-saved without losing image quality. Of course this is not the case when using the TIFF as a container holding compressed JPEG. Other TIFF options are layers and pages. |

| Grey component replacement |
|
Definition
| The Gray component replacement does not only add black to uncolored areas, but also to slightly colored ones, as black color is much cheaper than colored one. |

| An additive color model involves light emitted directly from a source or illuminant of some sort. The additive reproduction process usually uses red, green and blue light to produce the other colors. |

Subtractive color systems start with white light. Colored inks, paints or films placed between the viewer and the light source or reflective surface (such as white paper) subtract wavelengths from this white, and make a color.
Conversely, additive color systems start with no light (black). Light sources add wavelengths to make a color. In either an additive or a subtractive system, three primary colors are needed to match humans’ trichromatic color vision (caused by the three types of cone cells in the eye). |

| The two main benefits of the OpenType format are its cross-platform compatibility (the same font file works on Macintosh and Windows computers), and its ability to support widely expanded character sets and layout features, which provide richer linguistic support and advanced typographic control. |

| For Position Only. FPO is the placement of a blank placeholder or a temporary low-resolution illustration in the required location and size on the camera ready artwork to indicate where an actual image is to be placed on the final film or plate. FPO images are commonly used when you've been supplied actual photographic prints or other type of artwork to be scanned or photographed for inclusion |

| HSB stands for Hue, Saturation and Brightness. According to this model, any color is represented by 3 numbers. The first number is the hue, and its value ranges from 0 to 360 degrees. Each degree represent a distinct color. First there is the red color (0 or 360 degrees) and then there are all other colors (for example yellow at 120 degrees, green at 180 degrees and blue at 240 degrees), up to the violet color. All the rainbow's colors are represented here. The second number is the saturation. It represents the amount of color or, more exactly, its percentage. Its value ranges from 0 to 100, where 0 represents no color, while 100 represents the full color. Finally, the third number is the brightness. You can enhance the color brightness adding the white color, or you can reduce it adding the black color. In this case 0 represents the white color and 100 represents the black color. The more this value tends to 0, the brighter the color is. The more this value tends to 100 the darker the color is. |

| LAB stands for Luminance (or lightness) and A and B (which are chromatic components). According to this model A ranges from green to red, and B ranges from blue to yellow. This model was designed to be device independent. In other words by means of this model you can handle colors regardless of specific devices (such as monitors, printers, or computers). The Luminance ranges from 0 to 100, the A component ranges from -120 to +120 (from green to red) and the B component ranges from -120 to +120 (from blue to yellow). |

| Soft proofing is simply a mechanism that allows you to view on your computer monitor what your print will look like when it is on paper. A specific paper. That paper and ink combination has been defined by the profile that you or someone else has made for your printer / paper and ink combination. When a printer profile is made the colour of the paper is one of the factors that is figured into the profile, because the spectrophotometer is reading the combination of the ink, and the paper that lies beneath it. |

| The term "bit depth" is used to describe the number of bits used to store information about each pixel of an image. The higher the depth, the more colors that are available for storage. The bit depth of an image will determine how many levels of gray (or color) can be generated. |

| Moiré effect is a visual perception that occurs when viewing a set of lines or dots that is superimposed on another set of lines or dots, where the sets differ in relative size, angle, or spacing. The moiré effect can be seen when looking through ordinary window screens at another screen or background. It can also be generated by a photographic or electronic reproduction, either deliberately or accidentally. |
