Adobe Photoshop Printing Episode 1

Solve the mysteries of Photoshop printing with this step-by-step tutorial for Epson and Xerox printers. (Note: this is for printing from PhotoShop) Lots more great video tutorials at this Russell Brown site.
Mounting your Prints
Tuesday 23rd January 2007
Mounting is the technique used to secure a photograph to a mount or display board. There are several different methods and materials to choose from when mounting a photograph. Selection is based on several factors such as cost, convenience, equipment availability, and conservation. This site explains different methods to mount your exhibition print.
Qimage Print Quality Challenge
Wednesday 21st September 2005
From: Ken Rippengale
Are you up to testing your printer's resolution. When set to its highest interpolation setting (Max), Qimage sends data to the print driver at the resolution requested by the driver which is almost always either 600 PPI (Canon, HP and a few other printers) or 720 PPI (Epson printers). Before reading the quality challenge in the next section, you may want to test your printer if you need to be convinced that an inkjet printer can resolve detail beyond 200-300 PPI. Since the printer tests outlined in this section are performed by sending prints already prepared at the resolution of your print driver, this is not a test where we are comparing Qimage to other software.
We are simply sending a test image to the printer to determine the level of detail that can be resolved by your printer, paper, and ink. If you think or have heard from others that interpolating to 600 or 720 PPI is overkill, run the tests here first and judge for yourself, otherwise you can jump straight to the quality challenge.
Exhibition Paper and Mounting
Wednesday 24th August 2005
From: Ken Rippengale
Digital printing is revolutionising how we think about paper, how we buy it and how we use it. High quality monochrome or colour printing is no longer the sole preserve of the commercial printer. Technology has enabled short run production to the highest professional standards by anyone with a modest computer linked to a suitable printer.
More than ever, the quality of output is determined by the quality of paper or film used and in this environment whilst many companies sell paper, relatively few understand the issues involved and many traditional vendors, beyond having packets of paper on their shelves have little advice to offer.
This is the site for the serious user of paper, probably working from home or a small design office, wanting access to products, service and reasonably jargon-free advice or information.
Self-Adhesive Media Support and Mounting Card 200gsm
The freedom of Digital Fine Art and Photographic Printing has led to the development and use of a wide range of print media. Where window mounts are being used for display or exhibition purposes and only an edge tape is being used to position the print within the window, unsupported, they frequently are prone to bow, cockle or 'pop'.
Traditionally the alternative was to use an expensive backing board with either double-sided tape or spray-on adhesive. on-line media support card has been developed to give stability to any print. This self-adhesive 200gsm card has a special, non-migrating, aqueous (water based) latex emulsion adhesive coating to ensure good adhesion. Often self adhesive adhesives are solvent based or use solvent in the coating process; this uses water. The use of solvent in the dry cleaning process raised concerns with us about the possible effects of a solvent based adhesive on colour permanence etc. and for that reason they are offering the safer and environmentally preferable water based compound.
No more double sided tape, no more aerosol, just peel the backing paper off the support card, position the print on the adhesive coated support card, print side up, smoothing it down. Next, offer the window-cut mounting board gently onto the supported print ensuring that it is correctly positioned prior to pressing down onto the exposed adhesive surface. Press down onto the adhesive and trim off the excess from around the mount with a sharp knife to achieve a highly professional, flush supported print that will be resistant to distortion. Once pressed down the print will be securely supported and the bond should be considered permanent.

Have trouble remembering those paper sizes,. Not any more! You may find this site handy besides web tips using adobe photoshop this paper size table is very useful for reference (I know I can never remember what size A4 is exactly!). printout today
Photo Paper Sizes
Thursday 4st August 2005
From: Ron Shanks
Standard American photo paper sizes:
4"x6", 5"x7", 8"x10", also 8"x12", 12"x18", 16"x20", 16"x24", 20"x24", 20"x30".
Standard European photo paper sizes: 9x13 cm, 10x15 cm, 13x18 cm.
European Passport photo size: 5,12 cm x 3,84 cm (2" x 1.5").
Photo prints are based on the 35 mm photo film format:
- Format: 35
- Width: 36mm
- Height: 24mm
- Area: 864 sq mm
- Diagonal: 43.27mm
This standard ratio for 35mm negatives corresponds directly to print sizes of 4" x 6" and 8" x 12" and 20" x 30", and is fairly close to 5" x 7" (1.4:1) and 3.5" x 5" (1.43:1).
The aspect ratio of most digital camera pictures is not proportionate to the size of these standard photograph print sizes. Most digital cameras reproduce pictures in the aspect ratio of 3:4.
Some print services introduce now photo prints in the 3:4 aspect ratio.
It would be for instance a 4.5" x 6" paper print (11cm x 15cm).
Most document imaging resolution measures are in pixels (PICture ELement) per inch (or per mm - millimeter), and are commonly referred to as dpi (dots per inch) or dpmm (dots per mm). Most motion picture and still-photographic resolution measures are in pixels per image. This is most commonly seen in the 525 lines of NTSC (National Television System Committee), 625 lines for PAL (Phase Alternating Line) and SECAM (Sequential Couleur Avec Memoire or Sequential Colour with Memory), resolution of television images.
In pixels per image the horizontal resolution is given first. If the horizontal dimension is larger than the vertical dimension in pixels, the image or display is said to be landscape, if the horizontal is smaller, the image or display is said to be portrait.
- dpi: dots per inch
- ppi: pixels per inch
- lpi: lines per inch
dpi and ppi, lpi: For digital images, we are dealing with pixels and for printing we are dealing with dots and lines.
