Canvas Print Resolution and Colour Guide for Private Label Brands

A canvas or framed print can only be as good as the file it starts from. Printers cannot add detail that is not in the file, and they cannot guess what colour you meant. File quality depends on three choices made before the file is sent: pixel count, colour profile and file format.

This guide explains each in plain words for brands that buy wall art under their own label. It also shows where trusted sources disagree, because they do. Where they disagree, the sensible step is to ask your printer for its written file rules and follow those.

PPI means pixels per inch in the file. DPI is the older term and is often used to mean the same thing when people talk about files. What matters is the total pixel count and the print size you stretch it over. Change the print size and the effective resolution changes with it.

The sources we read give different targets. Printful recommends 300 DPI for its print files [1]. A university Epson printing guide asks for 300 dpi or as close as possible [4]. A canvas guide from a print service says to aim for at least 150 DPI at final print size, or 300 DPI if viewers will stand close, and gives an example: a 16 by 20 inch canvas needs roughly 2400 by 3000 pixels [5].

These are not necessarily in conflict. The sources differ on the figure, and close viewing pushes towards 300 [5]. Ask your printer which figure it uses for canvas.

• Check the image at 100% zoom on screen. If it looks soft there, it will look soft in print [5].
• Enlarging a small file does not add detail [5].
• Work out pixels as print size in inches multiplied by the DPI you need.

A gallery-wrapped canvas folds the image around a wooden bar frame, so the file must be larger than the front face. One print guide says to extend the image about 2 inches past the face on every side [5]. The same guide describes a slim 0.75 inch wrap and a deeper 1.5 inch gallery wrap [5].

If the picture cannot extend that far, the guide suggests keeping the subject centred and using a mirror wrap or solid colour edges. It also says to keep faces and text comfortably inside the face area [5]. Printers differ on whether they want the bleed in your file or add it themselves, so confirm this first.

For the construction side, see our guides on gallery-wrapped and framed canvas and the artwork file checklist.

The format affects file size, transparency and how much quality is kept. Printful suggests PNG for designs with transparency or detailed graphics, and JPEG for simpler graphics because the files stay small [1]. A canvas guide asks for a flattened, full-resolution JPG, TIFF or PDF at final dimensions with the wrap area included, and notes that flattening avoids linked-asset problems [5]. A university Epson guide asks for a flattened TIFF or PSD [4].

Two of the guides, [4] and [5], ask for a flattened file, and [5] also asks for full resolution. Printful [1] does not mention flattening. Which format is accepted is the printer's decision.

A colour profile tells software what the numbers in a file mean. sRGB is a standard default colour space [2]. It was proposed in 1996 by engineers at Hewlett-Packard and Microsoft [2]. Its authors aimed it at users who do not want to embed profiles in files [2].

An ICC profile is a device profile that lets colour management software convert colour data between a device and a device-independent colour space [3]. The ICC page says embedded profiles let users move colour data between computers transparently [3]. It also warns that perceptual rendering is vendor-specific, so different profiles can give different results [3].

Now the part where advice splits. Printful asks for sRGB (IEC61966-2.1) and says printers convert to CMYK after receiving the file, and that this conversion slightly changes colours [1]. A university Epson guide asks for a profile matching its Photoshop working space, Adobe RGB 1998 [4]. A canvas guide says to convert to CMYK before printing and to brighten shadows slightly, since matte canvas looks darker than a backlit screen [5]. The last guide does not name a profile [5].

All three can be right for their own printer and workflow. Colour rules are set by the print shop, and its software and inks decide what works. Do not guess: ask which profile to embed.

Use the table below as a starting checklist. It lists what each source says, so you can see where they differ and what to ask your printer.

Imagine a home decor brand wants a 24 by 36 inch gallery-wrapped canvas with a 1.5 inch deep edge. This is an illustration, not a real order.

1. Face size is 24 by 36 inches. Adding about 2 inches of bleed on each side [5] gives a file of 28 by 40 inches.
2. The printer says 150 DPI is fine for canvas. Pixels needed: 28 x 150 = 4200 and 40 x 150 = 6000, so 4200 by 6000 pixels.
3. The artwork is 3000 by 4500 pixels. At 28 by 40 inches that is about 107 PPI. That is below 150, and enlarging it would not add detail [5].
4. The brand can ask the artist for a larger master, shrink the print size, or ask the printer whether it accepts the lower figure for this image.
5. The brand also asks which profile to embed, and saves a flattened file only after that answer.

The point is the sequence: size first, then pixels, then profile, then format.
