Markzware‘s FlightCheck, the patented preflight solution to check prepress files for print quality control,
has Non-PDF Ground Controls. These include a Mode section under Images. This Images Mode section
offers the following Ground Controls:
- Bitmap
- Monotone
- Duotone
- Tritone
- Quadtone
- Grayscale
- Indexed Color
- RGB Color
- CMYK Color
- Lab Color
Read on to learn how these preflight features can help you.
Markzware FlightCheck 7.5 Mac Ground Controls:
Images Mode
Bitmap – This will trigger if a true bitmap image has been detected during preflighting. True bitmap images are typically bitmap TIFF images with resolutions over 1000 dpi. Many times people tint these bitmap TIFFs and use them for logos. Usually the use of bitmap TIFFs is not an issue for most people.
Monotone – This Ground Control will trigger if a monotone image created in Photoshop has been detected. A monotone image uses only one color to tint the image. In Photoshop you must first make and image grayscale before you can create a monotone image. Many times people will use a spot color to tint a monotone image. Depending on your workflow, monotone images may or may not be problematic. For typical 4-Color workflows the only time a monotone image would be an issue was if someone used a spot color instead of a process color to tint the image.
Duotone – This Ground Control will trigger if a duotone image created in Photoshop has been detected. Duotone images use two colors to tint an image.
Tritone – This Ground Control will trigger if a tritone image created in Photoshop has been detected. Tritone images use three colors to tint an image.
Quadtone – This Ground Control will trigger if a quadtone image created in Photoshop has been detected. Quadtone images use four colors to tint an image.
Grayscale – This Ground Control will trigger if a grayscale image has been detected. Grayscale images are essentially monotone images that use Black as the tint color. Normally grayscale images do not pose a problem in people’s workflows.
Indexed Color – This Ground Control will trigger if an image uses the Indexed color space. Indexed Color images are usually GIF files and are usually intended to be viewed as part of a page on the internet. The Indexed Color space consists of a max of 256 colors, so the image typically does not transfer well to print.
RGB Color – This Ground Control will trigger if an image is in RGB mode. Some people prefer RGB images and then do their own color conversion, some people prefer to receive images already converted to CMYK for print.
CMYK Color – This Ground Control will trigger if an image is in CMYK mode. Depending on your workflow, this may be what you want.
Lab Color – This Ground Control will trigger if an image is in Lab mode. Lab has a much wider gamut that CMYK, but unless you have color management in place, you may receive unexpected results if you convert between colorspaces.

FlightCheck warns of Bitmap, Monotone, Duotone, Tritone, Quadtone, Grayscale,
Indexed Color, RGB Color, CMYK Color, and Lab Color image modes.
