Steps to Create a Printable Proof Card

  1. Set the Correct Image Size and Resolution:
    • Determine the final print size of your proof card (e.g., 4×6 inches).
    • Set the resolution to 300 DPI for high-quality print output.
    • For a 4×6 inch card at 300 DPI, your image dimensions should be 1200×1800 pixels.
  2. Ensure Accuracy with a Scale:
    • Include a measurement scale (like a ruler) within the design of the proof card.
    • This helps verify that the printed size matches the intended dimensions.
  3. Use the Right File Format:
    • Save the image in a format that supports high resolution and does not compress the image, such as PDF, TIFF, or high-quality JPEG.
  4. Embed Print Instructions:
    • Include instructions within the file or as a separate document, guiding the customer to print at 100% scale.
    • Mention the importance of disabling any “fit to page” or “scale to fit” options in the print settings.
  5. Add a Note for Color and Print Settings:
    • Advise customers to ensure their printer settings are set to high quality or best quality for optimal results.
    • Mention the importance of checking printer settings for any color management adjustments.
  6. Test the Print:
    • Print a test version using different printers (if possible) to ensure the dimensions and quality are maintained.

Detailed Steps in Adobe Photoshop:

  1. Create or Open the Proof Card:
    • File > New or File > Open > Select your image.
  2. Set Image Size and Resolution:
    • Image > Image Size.
    • Ensure “Resample” is checked if you need to adjust pixel dimensions.
    • Set the resolution to 300 DPI.
    • Set the dimensions to the desired print size (e.g., Width: 4 inches, Height: 6 inches).
  3. Add a Measurement Scale:
    • Use the Line Tool or create a custom ruler graphic.
    • Place it at the edge of the proof card with clear markings (e.g., 0 to 6 inches).
  4. Save the Image in the Right Format:
    • File > Save As.
    • Choose PDF, TIFF, or high-quality JPEG.
    • Ensure “Embed Color Profile” is checked for color consistency.
  5. Embed Print Instructions:
    • Create a text layer with printing instructions, or include a separate instruction document.
    • Example: “Print at 100% scale. Do not use ‘fit to page’ or ‘scale to fit’ options.”
  6. Export or Print Test Version:
    • Print a test version to ensure accuracy.
    • Share the file with the customer and instruct them to print at 100% scale.

Example Instructions for the Customer:

  • Open the File:
    • Open the PDF/TIFF/JPEG file in a compatible viewer (e.g., Adobe Acrobat for PDF).
  • Print Settings:
    • Go to File > Print.
    • Ensure the scale is set to 100%.
    • Disable any “fit to page” or “scale to fit” options.
    • Set print quality to high or best quality.
    • Select the appropriate paper size (e.g., 4×6 inches if printing on a 4×6 photo paper).
  • Verify Dimensions:
    • Measure the printed ruler on the proof card to ensure it matches the intended dimensions.
    • If the dimensions are incorrect, adjust the print settings and reprint.
