How can I photograph large paintings for high-resolution stitched reproduction with minimal glare?

I need to digitize several large acrylic paintings (about 4×6 ft / 120×180 cm) for making large reproductions. I want files that are sharp, high resolution, evenly lit, and have little or no glare. My idea is to shoot multiple overlapping photos with a DSLR and stitch them into one larger image, similar to what phone scanning apps do, but with more control and better quality.
What shooting setup and workflow should I use for this? In particular:
- how should I light the artwork to minimize glare and keep illumination even?
- what camera position and lens choice help reduce distortion?
- is there software suited to stitching a flat artwork from multiple photos?
- how can I make the process efficient when photographing multiple paintings?

No app can change the lighting.
Photographing artwork for reproduction is a professional specialty. It uses well considered lighting in controlled conditions, high resolution cameras (often medium format), and lenses that cost "more than I paid for my first car" so to speak.
Multiple well placed lights plus a tripod for the camera is table stakes. A big space and a long lens makes placing the lights easier. The long lens reduces the angles which produce glare in the image. The larger space allows more distant light placements thereby reducing falloff from the inverse square law to even out the illumination.
The gear and technique need to be appropriate to the level of quality desired. A phone may or may not be sufficient depending on the goals for output and effort.
If quality matters a lot, it might be worth hiring a specialist. The top level of do-it-yourself, probably involves renting lights and camera gear. Below that you will probably need to invest a lot of time in fixing things with few guarantees that the input is sufficient to produce the desired output.

The key is to solve lighting first; stitching alone won’t fix bad reflections. For artwork reproduction, use a controlled setup:
- Place the painting flat and keep the camera perfectly parallel to it.
- Use a tripod and mark camera positions in advance for repeatability.
- Light the artwork with two good-quality lights placed symmetrically at about 45° to the painting.
- Put the lights as far back as practical to reduce falloff and make illumination more even.
- Shoot from farther away with a longer focal length, rectilinear lens to reduce distortion and glare-causing angles.
- Keep everything square and aligned; floor marks or alignment aids can help.
For higher resolution, shoot overlapping sections and stitch them as a mosaic/panorama of a flat subject. Hugin’s mosaic mode is a suitable tool for this.
If reproduction quality is critical, be aware that artwork copy photography is a specialized field; top results often use very controlled lighting and high-end gear. But with enough space, careful 45° lighting, a tripod, a parallel camera setup, and mosaic stitching, you can produce much better results than a phone scanning app.
