The Image list area offers you details regarding the images used in the document. There are 2 icons at the top left of the list which can be used at a glance to obtain instant information and are defined as follows:
Image Status Icons
•The “paint” column will display an icon based on the known application which created the image. Click and hold down the mouse button on this icon in order to view a list of the image’s colors.
•The “font” column will display an icon if the EPSF images is referencing fonts. A red icon will indicate that FLIGHTCHECK® has also detected something wrong with at least one of the fonts involved. Click and hold down the mouse button on this icon in order to view a list of the image’s fonts.
Image Name
Click on the word “Name” at the top of the Images list to toggle and display the list of images using their full pathnames, in which case you may want to resize the window to obtain a wider view.
Page
The Page column will display the page number on which the image can be found. To view the page numbers in a Section format, simply click the column header word “Page” (an “*” asterisk will appear). A “‡” character preceding the page number indicates the image is positioned entirely off the page. For PageMaker documents, the page number “†PB” will signify the image is on the pasteboard area of the document. In either case you should take note that any errors involved with this image have no true merit since the image will obviously not even appear on the printed page (but can affect the print job due to the needless increase of transmitted data).
Status
The Status column will display a message signifying the status of the image file. The word “OK” will mean that the image appears to be okay, in other words, the image has no apparent problems and can also be located and collected. The following is a list of other status messages which may appear, along with their meanings:
Status Meaning
Missing Image file cannot be found.
Modified Image file has been changed.
Off Page Image is outside the printable area.
Non-Print Image is suppressed from printing.
Stored Image is embedded in the document file.
Nested Image is within another image.
Size
The Size column will display the image’s physical file size (which can also be used later on to estimate the disk space required to Collect the image files). Note that an underlined value means the image has been compressed.
Type
The Type column will display one of the following image types:
JPEG Joint Photographic Experts Group (compressed)
Mode
The Mode column will display the image mode using one of the following:
Type Description
1-BIT Black and white
MONO Monotone
DUO Duotone
TRI Tritone
QUAD Quadtone
GRAY Grayscale
INDEX Indexed (1 byte RGB)
RGB 3 byte Red, Green, Blue
CMYK 4 byte Cyan, Magenta, Yellow, Black
A number following a mode will indicate the image contains additional channels, although most applications will usually ignore this data.
DPI
The DPI column will display the resolution of the image in terms of dots per inch. Note that you can click on the “DPI” column header to toggle viewing image resolutions by DPC (dots per centimeter). An EPSF (vector-based) image will show “n/a” (not applicable) for its DPI because by nature an EPSF is comprised of postscript drawing commands which can be acceptably printed within any spatial area or output resolution.
X%/Y%
The X%/Y% columns will display the horizontal and vertical scaling factors that have been applied to the image. If an image is scaled too high, it will print in “chunky” or “block” shapes. If scaled too low, then no additional quality is obtained beyond the threshold resolution of the output device.
Effective Resolution
The Res. column will display the effective resolution of the image. This is the result of multiplying the image DPI times the Y% scale factor. The vertical scale factor is used in the equation because this value can later be compared to the output lines per inch screening value.
