Colour Management made easier
By David Crowther
As my regular readers would know, colour management is an enabling technology. Within the ICC framework of device colour management, manufacturers are continually striving to make the management of colour easier.
Whilst the rules and methodologies of controlling colour have
remained stable for the past decade, the push into new markets, using
simplified solutions, is becoming more apparent. An example of this is
the recent release of ColorMunki Photo from X-Rite.
For the social, wedding and portrait photographers among us (along with
passionate advocates), the need for colour control and precision
without a degree in colour science has usually resulted in a blank
stare from colour management manufacturers and suppliers. Key segments
of the burgeoning photographic industry consider accurate colour to be
a key element to delivering a quality image. Many of the photographers
I have recently spoken to- including home enthusiasts, serious
amateurs, semi-professional and professional wedding and portrait
practitioners- have all been asking for an easier solution to colour
accuracy and predictability. ColorMunki Photo is not a “one size fits
all” solution to colour for photographers, but it is definitely a step
in the right direction. ColorMunki goes a long way to answering many of
the main colour related requests from photographers. What are these
requests?
1) A calibrated and profiled display that allows an accurate
simulation of the print, whether it be on cotton based fine art media,
canvas or a photo satin paper.
2) Automated help with configuration of applications, such as PhotoShop, for correct profile usage when printing.
3) Reassurance that images are viewed correctly at a client’s site.
4) The ability to create colour palettes from your images and other sources for image editing needs in popular applications.
Getting one’s head around building and using ICC profiles in one’s
workflow has proved to be a stumbling block for many. Lower cost
solutions for monitor calibration have been around for a few years now,
but many users have found managing the print side and sampling colours
to create custom palettes to be a winding and rocky path. ColorMunki
Photo offers huge breakthroughs in this area.
The actual ColorMunki device is an all in one compact
Spectrophotometer. The one compact unit will profile monitors, printers
and data projectors. It has an integrated white calibration plaque,
eliminating fiddly, easily lost small pieces and accessories. Display
calibration and profiling is taken care of with both easy and advanced
modes. If you’re no colour expert, the Easy Mode has a number of
presets to help to you choose settings. In Advanced mode, you can gain
control over white point, contrast, brightness and ambient light
measurements. Built in DDC auto detect control determines if the
monitor is compliant and if so, performs all advanced calibrations
automatically to create a monitor profile.
Whilst a calibrated and profiled display is imperative to accurate
visualization of colour, the actual display and its associated ICC
profile actually knows nothing about your printer/ink/media
combination. Therefore, good soft proofing techniques, together with
realizing the limitations that go with soft proofing- ambient lighting
conditions, SW or HW calibrated display, type and quality of viewing
system for soft proof/hard copy comparison- are paramount to
display/print matching. Printer profiling, both RGB and CMYK, is taken
care of with similar ease by utilising advanced technology that enables
a high quality ICC profile to be created from only 100 patches. This is
completed by measuring (through hand scanning) the first 50 patch chart
which provides enough information on basic printer behavior. ColorMunki
learns from this initial data capture to produce a second 50 patch
chart that fine tunes the colour accuracy. Scanning the charts is a
snap as the printed patches are quite large (see accompanying pic).
Whilst analyzing this product, I ran comprehensive tests comparing the
colour quality of the simplified 100 patch ColorMunki profile to
profiles produced from 900 patches and over by high end professional
profiling applications. Incredibly, the quality of the ColorMunki
profiles was almost equal to the high end profiles!
There is also a unique benefit to ColorMunki Photo in that it provides
the option to optimize your profile based on images for specific
colours. For example, if you are performing a portrait or wedding shoot
where the image capture falls under similar conditions, you have the
option to optimize the profile for specific colours or flesh tones.
When the time comes to print your images, ColorMunki Photo uses a
module called AppSet™. This helps enable your new profile as the
default in photo and design applications, as well as simplifying the
set up of the print driver.
ColorMunki Photo also offers projector profiling. Whilst it may not be
on everyone’s list for managing colour, for many photographers who
carry out big screen presentations to their clients, this is a welcome
inclusion. There is nothing more frustrating than trying to show off
your creative work only to be hampered by horrible unmanaged colour
from a data projector. The whole process is refreshingly painless,
involving positioning the ColorMunki to measure the projected colour
patches thrown up by the software. It only takes a few minutes and
really does work! It even takes into account the colour of the wall you
are projecting onto (if you are not using a projector screen).
Communicating images with clients, family and/or friends can be carried
out with the aid of another included application called DigitalPouch™.
This is a self executable Java based application. How does it work?
Images can be dragged and dropped into a pouch, ‘zipped’ up and then
sent to your client. Do they need a copy of ColorMunki? No. They will
be able to view the images, with the embedded profiles, in a replicated
viewing screen. DigitalPouch checks for, what X-Rite has called,
ViewSafe™ conditions in the recipients’ computer system for an up to
date monitor profile and provides a warning if it is unavailable or out
of date.
Finally, the creative side is well catered for. Colours can be
extracted from images within your image library automatically or
manually to create a custom colour palette. ColorMunki Photo also lets
you collect colour from any surface with a spot colour measurement
function.
This exciting new product will not fit everyone’s requirements, but in
my opinion, for those looking for entry level colour management on a
budget, it certainly ticks most of the right boxes.
