Optimizing File Size for Efficient Plotting

When preparing documents for plotting on HP DesignJet T1300 and T1700 printers, managing file size is crucial to ensure efficient processing and printing. Large files can significantly slow down the printing process, leading to longer wait times and potential workflow disruptions. 

Recommended File Size Limit

To maintain optimal performance, it is advisable to keep your file sizes below 50 MB. While files exceeding this size can still be printed, students should expect longer processing and print times, which may cause delays.

Impact of Large File Sizes

Files larger than 50 MB can cause:

• Extended Processing Time: The printer requires more time to interpret and process large files, delaying the start of printing.

• Increased Print Duration: Complex or large files can slow down the actual printing speed, leading to longer completion times.

• Higher Risk of Errors: Large files are more prone to errors such as incomplete prints or system crashes.

Best Practices for File Preparation

To optimize your files for plotting:

1. Flatten Layers: Ensure all layers in your document are flattened to reduce complexity and file size.

2. Embed Images: Incorporate all linked images into the document to prevent missing files and reduce processing time.

3. Convert Text to Outlines: Transform text into vector shapes to eliminate font compatibility issues.

4. Use Appropriate Resolution: Set image resolutions to a maximum of 300 DPI; higher resolutions unnecessarily increase file size without noticeable quality improvement.

5. Save in Optimized Formats: Utilize file formats like PDF that balance quality and file size effectively.
