How to Create a Pure Black-and-White PDF with Adobe PDF Printer
Question details
The user wants to generate a strict two-color (pure black and white) PDF using the Adobe PDF Printer without any grayscale or color elements.
- Product
- Adobe PDF Printer
- Device & OS
- not provided
- Scenario
- Attempting to print a document to PDF where all content must be strictly 100% black or 100% white, often required for specific printing presses or archival purposes.
- Observed behavior
- The Adobe PDF printer does not automatically force pure black-and-white output; instead, it preserves gray tones, colors, transparencies, and antialiasing from the original source file.
Ensure you have access to the native source file (e.g., Illustrator, InDesign, or Word document) because the color adjustments must be made within the original application before sending the print job to the Adobe PDF Printer.
Convert Source Artwork to Pure Black and White
The most effective way to produce a true 1-bit black-and-white PDF is to remove all color, grayscale, and transparency data directly within your source application before printing.
The Adobe PDF PostScript printer driver does not automatically strip out grayscale data. If the original content sent to the driver contains gradients, drop shadows, or antialiased edges, these elements will be preserved as gray tonal values rather than pure black or white.
Launch the application where your document was created (such as Adobe Illustrator, InDesign, or Microsoft Word) and open your source file.
Select all text, shapes, and vector elements. Change their color attributes to either pure black (CMYK: 0, 0, 0, 100% or Grayscale: G=0) or pure white (CMYK: 0, 0, 0, 0% or Grayscale: G=1).
Eliminate any elements that generate intermediate tones. This includes turning off drop shadows, removing gradients, setting images to a 1-bit monochrome bitmap, and disabling text or shape antialiasing.
Go to 'File' > 'Print' in your application, select 'Adobe PDF' from the printer list, and click 'Print' to generate the strictly two-color PDF.

Frequently Asked Questions
Why does my black-and-white PDF still show gray edges around text?
This is usually caused by antialiasing, a rendering technique used to smooth out jagged edges on screens. To resolve this, you must disable antialiasing or text smoothing in your design software before printing to the Adobe PDF printer.
Can I use Acrobat Pro to convert an existing PDF to pure black and white?
Yes. If you already have a PDF, you can use the Print Production tools in Acrobat Pro. Navigate to 'Preflight' or use the 'Convert Colors' tool to map all content to a pure black or dot gain profile, though modifying the original source file yields the most reliable results.
Does printing in grayscale guarantee a pure two-color PDF?
No. A grayscale PDF can contain up to 256 different shades of gray. A pure black-and-white PDF (often referred to as 1-bit or monochrome) strictly utilizes only two color values: 100% black and 100% white.
