Colour or grayscale printing: what does your file need?
Check whether colour carries meaning in your charts, tables and images. Use a sample page to choose a print mode without losing useful detail.

Choose colour when it carries information, such as categories in a chart or regions on a map. Black-and-white printing can suit text that remains clear without it. Make the decision from the hardest page in the document, preferably using a printed sample.
Ask whether the meaning survives
Imagine a chart with a red line and a green line but no direct labels. If both become similar shades of grey, the reader may not be able to identify them. Either keep colour or, if you can edit the source, add names and different line patterns.
A coloured heading above black body text may be purely decorative. Alternating table fills are useful only if the rows and figures remain distinguishable; matching the exact screen colour is less important than reading the data.
Grayscale and pure black and white differ
Presentation software may offer both grayscale, which retains intermediate tones, and pure black and white, which can omit shading and effects. Microsoft describes these colour options. Names vary between applications and printers.
Do not choose the harshest conversion simply because a document mostly contains text. Its photos, stamps or shaded sections may still need intermediate tones.
Run a useful sample check
- Choose a page with a colour chart, plus one containing shading or an image if applicable.
- Use a grayscale preview or prepare a grayscale test copy while retaining the original.
- Read every legend, table boundary and piece of text on a coloured background.
- Print a sample if differences in tone affect the meaning.
When editing the source, add labels or symbols rather than relying only on colour to distinguish correct and incorrect answers. For small slide thumbnails, test the handout layout at its final size too.
What if only some pages need colour?
Warqti sets the colour mode per file in an order, rather than per page within a file. Prepare separate files if sections need different settings, and check their names and order before payment. Colour availability and rates vary by shop; compare the displayed total rather than assuming a fixed price difference.
Keep the original colour document. Making a grayscale print copy should not remove the source you will need for future edits.
