CleartrreeeeCommercial Printing or DIY – you need this!l Most of this presentation applies equally to printing
yourself or using a commercial printer such as Chichester Uni Print Shop
l Aspect ratiosl Final sizingl Paper choice (or not)l Mounting your masterpiece
CleartrreeeeThe importance of Dynamic RangeOur eyes are very adaptive and they are also more sensitive to intensity than colour.
CleartrreeeePrinting uses a subtractive processl Additive colour mixing describes how the eye
interprets light to create our perception of colour.
l Subtractive colour mixing describes the colours that result when light absorbing substances are mixed.

CleartrreeeePrinting uses a subtractive process
RGB light processl Mixing Red and Blue displays Magental Mixing Red and Green displays Yellowl Mixing Green and Blue displays Cyan
CMYK print processl Mixing Cyan and Magenta reflects Bluel Mixing Magenta and Yellow reflects Redl Mixing Cyan and Yellow reflects Green!
CleartrreeeeSo – Printing is “different” to PDI/Web/TV/iPADl Smaller dynamic range so images look dullerl Uses subtractive colours not additive (counter intuitive!)l More capital outlay (for printer)l Higher running costs (media, ink, mistakes!)l But:
l Can be any size l Can make use of all your image information (5kx7k pixels)l Always available for display (no power needed)l Can be hung on your walll Can be put in an albuml Gives added “pleasure” to create l “Reaches the parts other formats cannot reach”!
CleartrreeeeDIY printing versus Use a service
DIYl Instant gratificationl Easy tuningl Wide variety of papersl Wide variety of finishesl “All your own work” BUTl Start-up costs are highl Paper costs can be highl Ink costs can be highl Needs some expertisel Can be fiddly
Servicel No printing expertise
neededl No start-up costsl No maintenance costsl Great paper (Archive
quality)l 24 hour turn around BUTl Limited choice of papersl Mistakes can be expensivel Tuning is in the hands of
the service provider
CleartrreeeeCommon tasks to both approachesl Choose aspect ratio for print (may be different to
paper)l Choose colour space/profile for printer/paper
combination (even for services)l Choose output format if using Adobe Elements
(jpg or PDF) depending on print requirementl Output density 300ppil For Bognor Regis Camera Club competitions:
l Prints need to be a minimum of 226 sq cm mounted on a card with a maximum size of 50cm x 40cm.
So what makes a print worth printing?
CleartrreeeeWhat makes a good Club Standard print?
l Communicates your vision, Why take it, why share it.l Fits the subject matter of the competition clearly, or
tongue in cheek?l Shows what you want to show unambiguouslyl Has immediate impact, but keeps the viewer interestedl Tells a story, ask questions of the viewer, creates an
emotional response in the viewer.l Should be simple, rather than busy and complicated with
lots of different points of interest.
CleartrreeeePhotographs that work …..
• are eye catching• are strongly composed.• have relatively few picture elements.• have no elements surplus to requirements.• use lighting and or surface reflections to achieve the best possible
tonality.• contain a limited colour palette which either contrasts or
complements each other• have an emotional message of some sort• leave you satisfied - but wanting more!• inform by showing the unusual, the unnoticed or interesting
juxtapositions.• tell a story or trigger memories• give you reasons to come back to the image again and again• have some extra magical thing about them

CleartrreeeePreparing an image for a Print Competition – Top Tips
l ‘Rules’ of composition have developed in painting and photography because the human brain seems to like these layouts. The rule of thirds is one of the commonest used. Sometimes breaking the rules works too …
l It is often said that odd numbers of objects are more satisfying than even numbered.
l Red coloured objects attract our attention, so add impact to an object or location in an image.
l Avoid things that distract from your messagel Horizons should be level and verticals vertical or obviously
angled.
l Come to our Composition workshop Sat 26th October
CleartrreeeePreparing a print for a Club competition – Top Tipsl Try to avoid losing bits of people or key features at the edge,
cutting off a head or missing the top of a spire can be annoying. However, a deliberate crop of much of a face draws attention to what you want to show.
l The eye is drawn to light and lighter areas in an image, so the part you want the viewer to concentrate on should be a little lighter than the rest. Bright areas away from your point of interest will draw the eye away, even more so at the edges.
l The important part of the image needs to be sharp. Generally, the foreground needs to be sharp. A landscape usually all needs to be sharp.
l Some photographs need blur to indicate movement or a dreamy atmosphere, this is different from being out of focus.
See the Basic Image Processing workshop Sat 16th Nov
CleartrreeeePreparing a print for a Club competition – Top Tips
l The way it is presented (mounted) should enhance and not detract from the print.
l The mount must be 40 x 50 cm portrait or landscape, and of an appropriate colour, eg white, black or cream. Whacky colours or mount holes don’t impress the judges!.
l The print should sit comfortably inside this mount, neither too big or too small, e.g. 20 x 30 and 30 x 40cm. Check if there is a minimum print size in the competition rules. Rectangle, square, letterbox all work well.
l The print should be of good quality on a paper that suits the image, if unsure, a low gloss is often a safe bet. Outstanding quality printing on special papers has high impact.

l Basic set-up (inside printer)l Basic printing (printer manages colours)l Crop for effect
CleartrreeeeCropping for effectl Metric papers sizes all have a common aspect ratio
mera sensors all have different aspect ratios!
l So images can’t be placed evenly on papers!

:1:1:1:1:1:1:1:1:1
CleartrreeeeSizing for printingl As with PDIs it’s better to resize an image to meet the
final print size using some principles:l Printing looks pixelated if the density is less than
200ppil So a 10”x8” print needs (10”x200ppi)x(8”x200ppi)=2000x1600 pixelsl The RICOH machine at the Chi PrintShop prints at 300ppi so that
would be (10x300)x(8x300)=3000x2400 pixels (for a 10”x8” print).l If you want to “go Large!” then an SRA3 image (45cm x 32cm) needs
5315px x 3780px to print properly

CleartrreeeeLightroom & Sharpeningl Three forms of sharpening need to be consideredl Input sharpening for RAW files (counteract effects of
bayer filter)l Performed in the Detail->Sharpening tab of Developl Defaults applied on import
l Creative sharpening (used to emphasise one part of the image over another)l Performed using the Gradient Filter and Adjustment/radial brush
in Developl Output sharpening (according to target media / device)
l Performed in the Print module (Print Job ->Print Sharpening) if printing or
l in the Export module for all others (Export->Output Sharpening)
CleartrreeeeOutput sharpening for Printing at Printshopl Output sharpening restores what is lost by the output
generation processl When Exporting to JPEG (as used by Printshop) use
Sharpen I normally use appropriate “Media” (Glossy) and “low” for sharpening
l Ensure that you export at 300ppi (to give image enough pixels to avoid jagged edges)
CleartrreeeeComplete Export parameters for Lightroom
CleartrreeeeExport converts eg RAW file to something to Print l File Settings
l JPEG, Quality = 100, Color Space = Adobe RGBl Image Sizing
l Resize to fit -> Take the largest dimension (L or W) you want your print to be, eg 29.7cm x 21cm (A4) or 42x29.7 (A3)
l Resolution -> 300 pixels per inch (What the printer needs)l Output Sharpening
l Sharpen for -> Glossy Paperl Amount -> Standard (don’t oversharpen!)
CleartrreeeeCheck list prior to sending to Printshopl What size do you want image printed?
l Should be in centimetres must be less than 45cmx32cml Have you got at least 300 pixels per inch in your image
l = 118 pixels per centimetrel Is the profile set to ARGB?l Have you exported image to JPG or PDF?l Have you specified which paper to print on in your
email?l Costs are £0.33p - £0.57p for SRA3 or pro ratal You will need to pay and pick up the images from
Bognor (cash only in the printshop)
CleartrreeeeSending prints off to Printshopl After checking your “exported” image
l ARGB, less than 45cm x 32cm, at least 300ppil Log onto WeTransfer.coml Enter name of the printshop as recipient
l [email protected] Enter your email addressl In the body of the email being prepared:
l Specify what size you want the images printed tol How many images there are to print
l Upload the image file (if one) or folder (if several)
l Wait 24 hours for a response (under normal conditions)

CleartrreeeeMounts for your masterpiecesl BRCC would like you to participate in competitions with
your works so the next step is mounting them. l You can do it yourself
l Purchase mountboard from eg Pullingers.coml Daler Rowney Standard Mountboard A1 (See colour swatch)l £3.35 for A1 size but min order is 10 (each is 594mm x 841mm) l Club specs are 500mm x 400mml Can get 2 mount boards per A1 sheetl Club has mountboard cutter for hire or you can purchase one
l Or purchase readymade mountboards with aperturesl From Cotswold Mounts
l https://www.cotswoldmounts.co.uk/products/white-core-mounts/white-core-single-mounts-additional-sizes to find 40x50cm size
l £2.00 (min order 4 for £7.97 inc vat) uses Daler-Rowney card
CleartrreeeeOther “bits” to complete your order!l Tape to stick your picture into the mount
l Self Adhesive Kraft Paper Tapel (£1.98 inc VAT from Cotswold mounts)
l Backing boards (to protect the back of the image)l ”Cheap” backing boards are available from Cotswold mounts
l Lightweight Backing Board 50cmx40cml £2.45 inc Vat for 4 (£0.62p each)l Or use blank SRA3 sheets at £0.20p each!
l Transparent sleeves to keep your masterpieces cleanl Presentation bags 50cm x 40cml 18p inc vat each from Cotswold Mounts
CleartrreeeeAperturesl How big a hole in the mountboard do you want/need?l Too big?
l Surround is too thin to separate image from edgel Too small?
l Image is lost in mountl Artistic decision but here are some pointers:
l Some images are square by naturel Some images are panoramic l Better to crop image (with frame) than to leave dead space
l Making mounts reusable lowers cost of entire processl I use four different aperture sizes and can always fit my
images within one of them!

l I have 4 different aspect ratios (to match 3 different apertures)
l “7x5” (-> 1.362:1) Prints to 32cm x 23.5cml “16x9” (-> 1.73:1) Prints to 32cm x 18.5cml “Panorama” (2.013:1) Prints to 32cm x 15.9cml Square (1:1) Prints to 20cm x 20cm
l These parameters are stored as presets in Lightrooml I purchase A3+ paper and always print 2 images to the same
sheet (2cm bigger than A4) (could use SRA3 equally)l Aperture size is 1cm smaller than print to ensure overlap
CleartrreeeeUsing this re-use approach with Printshopl Max paper size is 32cm x 45cml My max print size (“aspect ration 5x7”) is 32cm x
23.5cm (aperture is 1cm smaller)l Next one is (“Aspect Ratio 16x9”) 32cm x 18.5cm so
you can get 2 on a single SRA3 sheetl Next one is (“Aspect Ratio 16x10”) 32cm x 15.9cm so
you can get 2 on a single SRA3 sheetl Last is 20cm square image so you can get 2 per SRA3
sheet
