Drawing production method of design institutes

It was phased out over a decade ago, and the positions in photo development rooms were eliminated.

What is being provided to the construction party at the moment? Draw a blank sheet directly? Isn’t the cost higher than that of printing blueprints?

Paper costs just a few dollars; how much does a photo printer cost? How much does it cost to hire a draftsman?

Currently, the drawings provided to the construction party are in electronic format (such as PDF), which facilitates easy distribution and archiving. If a paper version is needed, it is usually printed on ordinary white paper. The cost is indeed higher than that of traditional blueprint printing, but there are more advantages: 1. **Higher efficiency** – After creating the drawing on a computer, it can be printed directly, eliminating the complicated processes of tracing onto sulfuric acid paper and then printing the blueprint ； 2. **Easy to modify** — Electronic files can be updated at any time, avoiding the waste caused by repeated scanning ； 3. **Lower overall cost** — Although individual sheets of plain paper are expensive, the savings in labor, equipment, and storage costs make it more cost-effective overall. In actual projects, white drawings are mostly used for ongoing communication, while for final archiving, a small number of blueprints are still printed according to standards (these days, blueprints are also often printed directly using large printers, without the need for acid paper for printing). In short, after the technological upgrade, efficiency takes precedence, and cost issues are resolved through optimizations in other areas. .

Now, design institutes print the electronic versions of the drawings directly onto blueprints. No base map is needed to post the image again.

Each drawing folds automatically after being printed. It can be bagged manually.
