How PH Firms Manage Large Drawing Set Printing on DesignJet

Many large projects in the construction and engineering industry need batch printing drawings numbering in the hundreds. These drawings must also be consistently high-quality, accurate, and current to provide engineers and other professionals with the resources they need at every stage. In the Philippines, it can be difficult to manage large drawing set printing projects like these, particularly when they involve multiple teams and frequent revisions before completion. As such, it's crucial to take steps to eliminate potential bottlenecks that might otherwise develop during export, plotting, or delivery.

Highly successful AEC firms look at these projects as processes as opposed to mere print tasks. Each process covers multiple steps from meticulous file staging and early sheet proofing to revision tracking and check standardisation, all of which come before actual plotting. With the right approach, you'll be able to minimise the risk of errors while keeping this process efficient from start to finish.

This article will look at the ways firms can develop a strong workflow through dependable large format printing setups, which facilitate consistent output for every page.

Preparing Files for Batch Printing Drawings

The first step with large drawing set printing involves file preparation. Using HP DesignJet technical plotters, firms can take the following key steps to prepare multi-sheet drawing printing projects:

1. Organise and consolidate CAD files into a single convenient folder. This will enable you to more easily complete batch-printed drawings.
2. Standardise drawing layouts with consistent print settings, including paper sizes, plot styles (e.g., colour or monochrome), fonts, layers, and scale.
3. Use your software's command for batch printing drawings, such as PUBLISH or AEPUBLISH in AutoCAD and BATCHPRINT in DraftSight.
4. Save batch setups as .dsd files in AutoCAD or .bpl in DraftSight to enable easy printing for future sets.

Proofing First Sheets Before Large Plot Runs

Another critical step requires proofing, which will help gauge the quality of the finished prints before completing your project.

In your software, check layer visibility to ensure all layers you want to print are visible during large drawing set printing. Also, make sure all text and symbols look right and that lineweights are consistent across drawings.

You can then print the first sheet of the set and confirm both scale accuracy and colour accuracy. Additionally, make sure your large format printer has enough paper and ink to complete the project.

Managing Revisions Across Multi-Sheet Drawing Sets

Over time, project drawings are likely to undergo one or more revisions. That makes it crucial to manage them all for each sheet.

To facilitate this, you can start by developing a unique revision history for each sheet if you need to make smaller changes. If changes are more extensive and complex, you may want to update the entire set with its own revision number. This organisational tactic can keep all of the sheets unified.

To help with revision management in multi-sheet drawing printing projects, you can also:

• Centralise all of your data within Autodesk Vault or other environments.
• Standardise numbering (e.g., 1, 2, 3 or A, B, C) to help keep track of all revisions.
• Mark any changes using clear visual indicators, such as triangles or revision clouds.
• Mark the author, date, and description of each change.

Reducing Bottlenecks in Large Drawing Set Printing

To prevent potential delays when batch printing drawings, there are some additional steps you can take, including:

1. Optimise digital files with vector processing to use up less memory than rasterised images.
2. Conduct audits before printing to mitigate the risk of errors.
3. Maintain a DPI of 150–300 for technical drawings, which provides sufficient resolution while maintaining efficiency.
4. Use a printer with multi-roll capability to enable projects to print continuously without running out of paper.
5. Implement smart scheduling to further ensure print projects finish on time, potentially switching between plotters based on project demands, e.g., using a faster plotter for black-and-white drawings and another for more complex colour prints.

Ensuring Consistent Output Across Every Printed Sheet

There are also some measures you can take to keep output reliably consistent with every multi-sheet drawing printing process.

For instance, in AutoCAD, you can assign specific lineweights to projects based on object colours using the CTB colour-dependent mapping option. If you're working with more complex projects across firms, you may opt for STB mapping, which assigns "Thin," "Heavy," or other styles, decoupling on-screen visual preferences from the completed print.

Another step you can take here is to check all colour modes, maintaining Cyan, Magenta, Yellow, and Black (CMYK) for all technical drawings, rather than Red, Green, and Blue (RGB), which is better for digital viewing.

Software like AutoCAD also allows for effective calibration, ensuring that a one-inch line on the screen translates into a line of the same length on paper.

Delivering Complete and Accurate Drawing Sets on Schedule

HP DesignJet printers also help AEC firms deliver finished, consistently accurate prints when batch printing drawings. To keep projects on schedule and deliver desirable end results, there are a few quick steps you can take. For example, before printing, you can conduct one last automated audit to locate any broken Xrefs, unreconciled layers, or other issues that could compromise projects. Another practice is to enforce strict quality control standards before completing multi-sheet drawing printing projects. Do one last check for:

• Layer management and consistency
• Clear dimensioning and annotation
• Revision tracking and version control
• Last-minute coordination checks
• Confirmation that the printer has enough ink and toner for the job
