UProof scans the page buffer folder selected in the configuration dialog and reads the header for each file. A page buffer contains a compressed or uncompressed bitmap of the page, and the header describes the parameters of the bitmap and print job including title, height, width, bit depth, negative, mirrored, page number, and color name and value. Plates are grouped by their unique reference number within the header. When a job is transferred to the queue, the user selects the desired actions to be performed, which are as follows:

Individual page buffers are merged into a compressed tiff file using an input and output color profile.

The master file is used to create a 288 pixel square preview file. All image files are stored as compressed PNG image files.

The master file is used to chop the image into 288 pixel square tiles, and stored into an indexed flat file for rendering by the PHP application.

The files that were created in the previous step are transferred via FTP protocol to the web server using information provided on the configuration screen. Files are stored in a folder with a hard-to-guess location, providing a reasonable level of security.

An HTML email message is created and sent to each selected recipient along with a preview of the first page of the job and a link to view the job.

Once the recipient receives the email, the link it contains is used to launch a browser to preview the job on screen. Links within the web page allow the viewer to send an email to either accept or reject the job.

UProof can often run on the RIP computer because the threads it uses run at idle priority level, which means any other thread in the system can interrupt any UProof thread to perform work. Additionally, UProof uses little memory by using banded tiff files and small PNG files to create images.
