One of the elements I picked up as an output for evaluation from assignment 3 was to look at printing at home. I had looked at this earlier in the course and decided to print from home my assignment 2 submission. I was not satisfied with the printed output from Assignment 2 and the feedback from my tutor pointed out the print colours were flat, I had assumed as they were submitted on a matte paper. I chose to use Loxley (whom I send any client printing to) for Assignment 3 prints submission partially due to the large areas of black in the image. Since then I have been experimenting with different paper types obtained from Hahnemuhle, Fotospeed, Canson and Marrutt. Various threads on the OCA forums advise against using glossy paper for assessment submission and in the feedback from my tutor for Assignment 4 Helen advised using a good quality lustre or even a fine art baryta giclee process.
Printing workflow starts with the image itself and ensuring you have the correct white balance setting in the camera at the time of capturing the image. There are aids on the market which can be used to assist in getting this right at the point of image creation to then assist with post-production such as ColorChecker  and in the same family range, the cube can be used to check white balance, exposure and brightness levels. Essentially these have known colour swatches printed onto the target and one of your test shots needs to include the colour target full screen and in the same lighting conditions, in post-production, you can then select the colour target and adjust all of the subsequent images and maintain the colour balance. This can further be corrected in post-production and refined further if you are shooting in RAW. Before any image manipulation is undertaken your screen needs to be calibrated and if you’re then printing the printer needs to be calibrated to the type of paper it’s printing on.
For screen calibration I use a Spyder 4 by Datacolor, this is straightforward to use and includes a piece of software to control the calibration device. To calibrate your screen(s) you start the software and hand this device onto the screen, the software then projects a number of colour swatches on the screen and the device reads the colour value and the software then compares the known value to the actual output and creates a profile for that screen. Your screen profile is then adjusted to match this new profile and any colours/lightness/darkness on the screen should then match the image you’re working on. A reminder is normally set in the software settings to re-calibrate the screen at a specified interval to ensure consistency. There are numerous walk through videos on YouTube on how to calibrate a screen, a useful walkthrough of the process here  by Damian Symonds and  here by Northlight Images.
The next step is to then calibrate your printer to match the screen. There is an individual ICC profile for each paper/ink combination. Generic profiles are included for each printer, in my case I use an Epson SC-P800 printer, to be used for the manufacturer specific available papers. For each type of aftermarket paper, generic ICC profiles can be downloaded from the manufacturer’s websites(I’ve listed below the ones I have used). Given that each screen needs to be individually adjusted it then follows each paper/printer combination also needs to be checked as the generic profiles will only go so far. With manufacturing tolerances and technology, you should expect them to be fairly accurate, there is very much debate and technical conversation on gamut, paper evaluation, printer specifications etc and I’ll be clear with this blog I’m not going into that detail just on how.
Producing a specific ICC print profiling can normally be obtained free of charge, you need to buy a box of your chosen paper type (A4 size) and then print onto it the test target. Test targets are supplied by the manufacturer, in the case of Marrutt instructions are emailed and you download the profiles (before and after) and a link to the Adobe Colour Printer Utility which is used to print the test target .
The is then left to dry for a few hours to prevent smudging, once dry it can be posted to the manufacturer. They scan this using a Spectrocolorimeter and compare the recorded values against the test print expected values. I did also buy a sample pack from Fotospeed and send them all back for profiling, needless to say the response I received was not favourable and they only chose to profile a few of their most popular papers as they had better things to do with their day.
An ICC profile is created which is specific to your printer and paper type. This profile is emailed back to you in a couple of days which you then install on your printer. A further test print is made using an evaluation target  which is then sent back to the manufacturer. The evaluation print is then checked to ensure the profile generated is as intended. Manufacturers recommend the print profile are tested every 6 months to ensure consistency.
I have purchased papers from the following suppliers:
I have profiled the papers from Marrutt. Marrutt provided detailed information on how to undertake the print profiling on their webpagesand initial instructions via email. With the exception of one profile, the process has performed as expected. The failed profile for their gloss paper had noticeably reduced red values when first installed. I repeated the process using the test target and sent this back again to be re-profiled, the second profile was better. I did struggle with some of the smooth art papers as to which was actually the print side.
Print calibration can also be performed at home, you will need to use a device that not only calibrates your screen but also can read and then calibrate any printed pages. Two of the most common devices are the Spyderprint manufactured by Datacolor  where there are two separate devices and the ColorMunki Photo  by X-rite  which is combined into one device.
