Summary
The HP Advanced Profiling Solution (APS) powered by X-Rite is an
integrated solution for calibrating and profiling monitors, profiling
HP Designjet Z Photo Printer series and for validating and
optimizing ICC profiles.
A number of profiling solutions are available ranging from the in-the-
box HP Easy Profiling Solution (EPS), over optional software and
hardware bundles like APS, to high end stand-alone software
packages
like
X-Rite
ProfileMaker,
Monaco,
or
Heidelberg
PrintOpen. The features and price points of these solutions vary
widely, from very easy to use and included in the printer purchase price, to quite
sophisticated and expensive.
The HP Advanced Profiling Solution powered by X-Rite represents a reasonable
middle ground with respect to features and price. All solutions provide good
colorimetric accuracy, but especially the details of perceptual rendering intents can
and do vary. As usual, the best advice is to compare carefully and use the most
fitting tool for the job.
In the following pages we describe in detail the HP Advanced Profiling Solution
(page 2-5) and we provide a comparison to other profiling solutions (page 6).

  • Page 2 What is the HP Advanced Profiling Solution (APS)? The HP Advanced Profiling Solution (APS) powered by X-Rite is a software and hardware package for generating ICC profiles, with a wizard style user interface. It uses the HP Designjet Z Photo printer series’ Embedded Spectro-Photometer (ESP) for printer profiling, and an in-the-box X-Rite Eye-One Display 2 colorimeter for monitor profiling.
  • Page 3 digital color management. A number of options are provided for monitor calibration (white point, gamma, and luminance) and for Z series printer profiling (chart size, profile size, gray axis style, and viewing light source). The printer profiling parameters user interface is shown below. The standard RGB driver print path can be profiled via an on-line workflow (with integrated chart printing), and third party print paths (e.g.
  • Page 4 The printer profile editing user interface is shown below. What does APS APS does not create ICC profiles for scanners, digital cameras, or other kinds of input devices. It does not work with X-Rite Eye-One or other standalone colorimeters or spectrophotometers for printer profiling. While it has a number of parameters for monitor and printer profile creation, it does not have the sophisticated separation or black generation, gamut mapping style, and other controls that some profiling packages offer.

    It does not allow low level editing of render tables or other ICC profile tags (components). Does guarantee perfect match monitor (WYSIWYG No, it does not, and no profiling package does. A color match implies no perceivable difference (or zero delta-E) between one medium (the monitor) and another (the print), even when seen side by side.

  • Page 7 How does APS compare to other solutions? In general, we distinguish a number of different profiling solutions for the HP Designjet Z Photo printer series, which we will group into levels: A. In the box: Every HP Designjet Z Photo printer series comes with a complete printer calibration and profiling solution in the box, known as the HP Easy Profiling Solution (EPS).

  • Page 9 Colorimetric accuracy Color profiles can be evaluated numerically with regards to color accuracy, which is relevant e.g. for proofing applications. The figure below illustrates typical print- and-measure color differences in delta-E (1 dE being the smallest perceivable difference in theory) for the 46 colors represented in the FOGRA color control strip processed through the same ISO coated input profile and different HP Designjet Z3100 Photo Printer output profiles generated with different profiling...
