Colour is one of the trickiest aspects of photography and print. The same photo can look noticeably different on your phone, your laptop, and on paper - and that's not a fault, it's just the nature of how different devices capture and reproduce colour. This article explains why, and what you can do to get the best results from your RapidStudio prints.
Why does colour look different across devices?
Every device - your camera, your phone screen, your monitor, our press - has its own unique way of capturing or displaying colour. Several factors contribute to this:
Gamut
Gamut refers to the full range of colours a device is capable of reproducing. A wide gamut means the device can accurately represent more colours; a narrow gamut means some colours will be approximated. Your camera, your monitor, and our press all have different gamuts, which is one reason the same image can look slightly different on each.
Backlight
Your monitor produces its own light, which makes colours appear significantly brighter and more vivid than they can ever look on paper - which only reflects light rather than emitting it. This is one of the most common reasons a print looks slightly darker or less vibrant than the same image on screen.
Colour temperature
Colour can be shifted to appear "warm" (orange-yellow) or "cool" (blue). Most monitors have a colour temperature setting that can be adjusted, and many people shift it to their preference without realising it affects how photos look.
White balance
Cameras analyse the light in a scene and apply a correction to make the image look natural. Different lighting conditions - sunlight, fluorescent, incandescent - produce differently tinted light, and the camera's white balance setting compensates for this. When it gets it wrong, photos come out with an orange, yellow, or blue tint.
Common colour problems and what to do
Blown-out highlights (pure white areas)
This is the most important one to watch for. In print, white is simply blank paper - no ink is placed there at all. If a bright area in your photo contains pure white (no detail at all), it will print as a stark, flat white patch that can look unnatural and harsh, particularly in skies and skin.
Many cameras can highlight blown-out areas on the screen after you take a shot - look for a "highlight alert" or "blinking highlights" setting. If you see it, try adjusting your exposure and retaking the photo.
White balance issues
If your photos have a colour cast - everything looking a little too warm or cool -try correcting this in a photo editing app before uploading. Lightroom, Snapseed (free, mobile), and Apple Photos all have white balance correction tools.
Skin tones
Our eyes are particularly sensitive to how skin looks, so even a slight colour shift can be noticeable. Skin that looks fine on screen can come out a little too red, too yellow, or too pale in print. If you're printing portraits, it's worth checking your skin tones carefully before ordering.
Should I use RGB or CMYK files?
Use RGB - always.
Most people have heard that professional printers ask for CMYK files, and wonder whether they should convert their photos before uploading. For RapidStudio photo products, please do not do this - here's why:
Your photos are captured in RGB. Your camera, your phone, and every screen you view images on works in RGB (Red, Green, Blue). This is the native format of digital photography.
We handle the conversion correctly. Our digital press has a wider colour gamut than the CMYK standard - meaning it can reproduce a broader range of colours than a typical CMYK workflow allows. We apply a carefully calibrated conversion that is optimised for our specific equipment and papers, giving you the best possible colour accuracy.
Converting to CMYK yourself will make things worse. Standard CMYK conversions compress the colour range and are not calibrated for our press. If you upload a CMYK file, the colour will be less accurate, not more.
JPG files are always RGB - this is correct. If you have files in CMYK format (sometimes produced by design software like Photoshop or InDesign), save them as RGB before uploading. If you need a CMYK file for another purpose, save it as a TIFF or PDF - do not save a CMYK JPG, as this is not well supported and will produce poor results.
Practical tips for better colour
- Trust your camera screen more than your computer monitor - camera screens are typically more colour-accurate than uncalibrated monitors.
- If your monitor is old, colours on screen may have drifted significantly. Try viewing your images on a second screen or device to compare.
- If you edit your photos, do so on your monitor's default colour settings - custom "warm" or "vivid" display settings will skew your edits.
- Avoid cropping or enlarging images in ways that reduce their resolution - this can affect both sharpness and tonal accuracy.
- For the best results, use the original files from your camera rather than copies shared via WhatsApp or social media, which are compressed and may have had colour processing applied.
