Tutorial - Comparing braille

ArtProof performs a pixel-based comparison between two digital files. It supports PDF, AI, TIFF, BMP and JPEG. It quickly detects and identifies missing text, graphics, incorrect fonts and text sizes, as well as broken type and color deviations.

In this tutorial I focus on the Braille tool. The tool detects braille region(s) in both master and sample file. There are two options available:

Braille Translation: Detects and translates braille and displays information about the braille dots such as the language and number of dots.
Braille Compare: Compares braille regions that were detected on the sample against the detected braille regions on the master.

I will show the comparison of braille in a folding carton job. This will be done between the original (master) and the production PDF file (sample).

Launch ArtProof

Load the master PDF file "Carton job_Master.pdf"

  1. Double click in the Master panel to launch the file load dialog box and navigate to the folder where the master PDF file "Carton job_Master.pdf" is located.

The master PDF file is the original file.

Prepare the master PDF file for inspection in the PDF Viewer

  1. Click "Accept Changes".

The PDF file itself is not changed.

Load the sample PDF file "Carton job_Sample.pdf"

  1. Double click in the Sample panel to launch the file load dialog box and navigate to the folder where the sample PDF file "Carton job_Sample.pdf" is located.

The sample PDF file is the production file.

Prepare the sample PDF file for inspection in the PDF Viewer

  1. Click "Accept Changes".

The PDF file itself is not changed.

Compare the braille between the master and sample file

  1. Go to "Braille"
  2. Click "Language".
  3. Select "Braille".
  4. Click "Compare".

Analyze the braille comparing

The braille regions are auto-detected, highlighted, numbered, translated and compared.

Review the second braille region

  1. Select braille "Region 2".

The braille region is magnified. In the braille region there are differences between the compared PDF files. Missing and extra dots on the sample are identified in the Inspection panel.

  • Missing dots are highlighted in a red circle with a "minus" sign.
  • Extra dots are highlighted in red with a "plus" sign.

Open the Report dialog

  1. Go to "Generate Report".

Generate the report

  1. Enter the product ID "1".
  2. In the Status drop down list choose "Fail".
  3. Enter the product name "Carton job braille".
  4. Enter lot "1".
  5. Enter your name.
  6. Enter the comment "Braille is not ok. Check braille region 2!".
  7. Click "Save".

NOTE: I put the status on "Fail" because there is a braille difference in region 2.

Save the report

  1. Save the report as "Carton job_Braille_Report".
  2. Click "Save".

Analyze the report

The inspection results of the braille comparing are included in the report. The report has an overview preview of the inspected braille regions, a detail preview of each braille region with details, translations, comparisons and the added comments. This PDF report has to be send to the person who is responsible for the corrections.
