Steps to Create a Printable Proof Card
- 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.
- 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.
- 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.
- 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.
- 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.
- 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:
- Create or Open the Proof Card:
- File > New or File > Open > Select your image.
- 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).
- 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).
- 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.
- 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.”
- 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.
