NOTE: 

A company’s logo or address can be inserted in the top of the report. To do so, a file with the 

size 20 x 80 mm has to be made as a JPEG-file. 
 
In the data directory where the software is installed, C:….\proovePCdata, a file with the name 

Prooveit 

User Logo.jpg

 is located. By default this logo will appear on the report. The logo looks as follows: 

 

 

 
To  change  the  logo,  the  JPEG-file  with  the  company  name  has  to  be  renamed  to 

Prooveit  User 

Logo.jpg

 and has to overwrite the existing file. 

 
If a report has to be made without a logo, the file “

for a blank logo rename this file to Prooveit User
