Along with the descriptions of the master images, there is an example image of what they are next to it.
Bitmap
A bitmap image can only be black and
white with no shades of gray. A signature scanned in can be a sharp, high
resolution bitmap image. Most of the time bitmap images are drawings or things
that are scanned in black and white. The file is labeled .bmp for bitmap.
Reverse
A reverse is anything in print that
allows the paper to show through. For example a black background with white “ink”,
the “ink” is actually the paper showing through. It can be text, part of an
image, illustration, or anything that allows the background to show through as
the “white” area.
Vector Art
Vector art does not contain pixels so it can
be scaled to basically any size and the image still be crisp. Vector art is
created in Adobe Illustrator, and can be any color you want. Although it is
created in Illustrator it can be exported as different file formats such as a
PDF. Traxson's Rescue logo is also an example of vector artwork.
Grayscale Raster
A grayscale raster is an image saved in
grayscale color mode, which is black and white. Rasters can be saved in
different formats such as .gif, .jpg, .tiff, and bmp. The image represents the
information which is translated into pixels on the computer. A raster is a
basic photograph, and one in grayscale is with the color removed from it.
Duotone Raster
A duotone raster is an image using only two
colors, usually black and a spot color. To make a duotone you have your raster
image and simply change the mode to grayscale, and then duotone. This format
file will be an EPS file.
Silhouette Raster
A silhouette raster is taking an image in
Photoshop and outlining it making a silhouette out of it. After having the
image outlined that you want to be taken away from the photo and viewed without
the background, you will save it as an eps as the last part of creating a
silhouette raster. It can be in any color mode.
Full Bleed Raster
A full bleed raster is any image, saved in
tiff, jpg, bmp, that bleeds of a page on all edges. It is a large image that
takes up a page and goes to the bleed marks to be trimmed.
Four Color Raster
Is any CMYK raster image. It is called four
color because it uses the cyan, magenta, yellow, and black ink to create the
image. Can be saved in any of those raster file formats.
Screen Tint
A screen tint pattern has dots that are all
the same size and create an even tone. It is a “dulled” color of a spot color,
meaning it uses the same color but may not have the same heavy overlay. It
could be the color at 50% almost like an opacity.
