9. Use the [PDF overprint simulation] function to make opaque objects look transparent.
Underlying objects become visible. If this function is disabled, the colors on top will knock out
all underlying colors.
10. Use the [Use PDF/X output intent] function to indicate if PDF source files are printed
according to their embedded output intent. PDF/X specifies the printing conditions for which a
PDF/X file is created. These printing conditions are called output intents. The printer can
handle PDF/X compliant PDF source files. Then, the output intent overrules the DeviceCMYK
rendering intent and DeviceCMYK input profile.
11. Use the [Overprinting black] function to force the printer to print pure black text and graphics
over the background color. The [Overprinting black] prevents that white lines appear around
black characters and graphics.
• [As in document]: overprinting black is not applied.
• [Enabled for text]: overprinting black is applied to texts.
• [Enabled for text and graphics]: overprinting black is applied to texts and graphics.

12. Use the [Preserve pure black] function to apply pure black preservation when possible. Pure
black preservation means that the color black is composed of 100% K ink. When pure black
preservation is not possible or disabled, the color black is composed of a mixture of two or
more C, M, Y, and K inks.
13. Use the [Black Point Compensation (BPC)] function applies to the relative colorimetric
rendering intent. Details in dark regions of the document can be lost with the standard color
conversion. The Black Point Compensation aligns the darkest level of black achievable (black
point) of the source to the darkest level of black achievable on the printer.
• [Disabled]: Black Point Compensation is not applied.
• [Adobe BPC]: the Adobe implementation of [Black Point Compensation (BPC)].
• [Enhanced BPC]: when the black point in the document is rather light, select [Enhanced
BPC].
