Colour Management

Screen Calibration

The first step in getting good, consistent colours in your prints is ensuring your monitor is well calibrated. In order to properly calibrate your monitor you will need an external device such as a datacolor spyder.

Lighting

Another important factor not to be overlooked is the ambient lighting around your screen. The closer the ambient light is to true daylight, the better. As a general rule of thumb, desk lamps and traditional household bulbs have a low CRI (Colour Rendering Index) which is probably around 70-80 of a possible 100, this results in the human eye seeing a colour shift when viewing your screen. The lighting in our laboratory is controlled to a CRI no lower than 98, meaning we can ensure consistent colour corrections across the whole colour spectrum.

Colour Profiles

The colour profiles we provide are for the purpose of soft proofing your images (they should never be embedded into an image). For best results you should provide jpeg images in either SRGB or Adobe98 colour space.

The purpose of soft proofing is to highlight areas of your image which may be outside the range of gamut achievable by printing photographically. This therefore would enable you to adjust your images to effectively pull them into a printable colour spectrum.

Please note however, if you order a lot of prints, applying this process to every image would be a daunting task. As a general rule of thumb, most images will be ok. It is usually only images with extreme colours such as intense yellows, greens and violets that may show up an issue.

When printing an image in either SRGB or Adobe98 colour space, out of gamut colours are progressively ‘pulled’ into range. This is done by adjusting all levels of that particular colour so that you would never realise there had been an issue.

We offer a free colour correction service on all images that pass through our laboratory (unless you specify for us not to). Our colour correction is carried out by skilled technicians. If you opt to use this service, you should not need to do your own profiling. If however you would rather do this yourself, you can download and use our icc profiles for soft proofing which are generated from our calibrated printers.

Soft Proofing

Download your desired profile above

Unzip the profile.

On a PC:

right click on it and select ‘install’.

On a Mac:

Move the profile into Library\ColorSync\Profiles

Open Photoshop.

Select View --> Proof Setup --> Custom

Under ‘Proof Conditions’ set the ‘Device to Simulate’ to ‘OneVisionImaging-Lustre’ etc

Set the ‘Rendering Intent’ to ‘Perceptual’

You can save these selections for future use at this point if required.

Photoshop Help Instructions

Exit the dialog and return to your image. Pressing Ctrl+Y will now toggle between your original image and an emulation of how it may look when printed (Your image remains unchanged on your hard disk).

The image may appear dull as Photoshop attempts to reduce the affect of a bright screen.

Pressing Ctrl+Shift+Y will toggle between your original image and showing you colours which are out of gamut. Out of gamut colours will be highlighted in a light grey colour. If you don't see that happen then all of your colours are within range.
