Master Image List

Bitmap Images also referred to as "line art images", bitmaps consist of only black and white pixels with no shades of gray. When scanning a signature or a ink drawn image, a bitmap is able to give you that sharp clean image with a high resolution.  Since bitmaps tend to be small and compact they are able to have a high resoultion generally 600-1200ppi but are still capiable of having a small file size.

A Reverse is used when oppostie colors are being used in the production process.
Reverse printing is different from normal printing due to the fact that contrast is created on the paper. Here is an example of a reverse.


Vector art is made up of illustrator images which have been exported into EPS files.

Grayscale raster datasets contain values between 0 and 255,0 is black, 255 is white. The numbers inbetween are increasingly lighter shades of gray. Grayscale rasters have the abality to be saved as an illustrator file and be chnaged around in photoshop, after these steps is it then able t be placed into InDesign files.

Duotone rasters consist of two, three or four different color. Duotone are able to be created in photoshop but have the ability to be saved in several formats.

A silhouette raster is when you use a clipping path to select an object within an image that you want to appear on a different background in InDesign. All files for print are able to be every color mode but not RGB and is besed when saved as an .eps.   Also the file should a minium of  300 resolution.

A full bleed raster is any image brought in from Photoshop that is going to bleed on all sides of the document.  This can be in all colors modes but,RGB. Th image should be a minium of 300 ppi and  saved as a .tiff or .eps.

A four color raster is a raster image which is in full color. This raster needs to be CMYK and 300 you can oable to save four color rasters as  .tiff or flattened .eps file. 
A screen tint is a block of color on an image or document that is made up of dots of color rather than a solid block of color.
