I work at a PVC wall decorations factory, where I operate a single-pass industrial inkjet printer. It's not the kind of printer that can be networked or accept postscript jobs.
I'd like to help improve image editing and color management to save time and improve color consistency.
Three proprietary Windows programs are used, Adobe Photoshop, a RIP program and a post-processing program. Currently, copies of these programs are installed on several laptops, large TIFF files are copied over a slow internal network to process them locally, then copied to another smb share, ... while also backups of the wrong files are made, because of the current situation.
When it comes to running the proprietary RIP program, there are two important limitations to consider:
it requires a Sentinel HL usb hardware token to run.
it has a limited license (multi-user and backup feature is missing): ideally only one instance of the RIP should run.
I think they bought a USB server to allow easy usage of multiple installs. But with concurrent users, sharing the state in C:\ProgramData\<RIP-program>\... could crash the program, and it is harder to make backups of that folder.
The company has on-site servers. I'd like to explore running a Windows VM on one of these with an Arch Linux host running Openzfs, Looking Glass, with access to a particular VLAN. We could make good use of the server's resources (lots of CPU cores, GPU passthrough for Photoshop), while solving the two limitations listed above, and safely storing the original TIFFs where they're needed (zfs raidz...).
The RIP can run headless for most tasks, with the Sentinel HL dongle plugged in the server, and I can further automate the GUI with Autohotkey and UIA if needed. In order to use Photoshop interactively, however, we'd need to stream the Virtual manager Wayland client from a user session on the server over the LAN (not a remote session but mainframe-like).
So here are my questions.
Is Waypipe suitable and sufficient to transmit the qemu client window over LAN? Isn't there a project that uses WebRTC to stream a Wayland screen in the browser?
Can I make sure that a calibrated laptop screen shows the right colors with a setup like this? Looking Glass should not apply icc profiles when gaming, but is this true when proofing an image on-screen in Photoshop?
I'm concerned about security. Am I making sense? What would you do?
