The range of photographic media for photo-art reproduction has grown apace in recent years. For serious and occasional collectors alike, it pays to understand the differences in methodology, and the potential effect of acquisition prices and the investment value for the years ahead. Here are some key terms and the processes which apply to them

C-Type Prints

Darkroom/wet prints made from colour negatives or transparencies. Before digital technology, these were the prints we all received from the pharmacies from our holiday films. They were also produced in larger sizes for exhibitions. C-type prints are now archival and are still preferred by some photographers and collectors to digital art prints.

Fine-art digital prints, aka Giclee, Iris or Art inkjet prints

The most common way of producing collectable prints in the digital age, is by scanning the original negative, or balancing a digital file from a digital camera, and out-putting the image, usually retouched, on various media types using archival inks. The advantage is that very fine quality coated papers can be used to make delicate, beautiful prints. Rockarchive’s Edition 100 is made in this way in various sizes without any loss of quality.

Lamda or Lightjet

This mode of printing contains elements of both traditional darkroom printing and digital technology. The original negative is scanned, or a digital image adjusted, and the resulting image is outputted onto photographic paper by means of laser light. The prints have the same archival value as traditional photographic RC prints or C-type prints on plastic based papers, with the advantage to some collectors of being called ‘photographic prints’.

Lenticular

Lenticular printing is a multi-step process consisting of creating an image from at least two existing images, and combining it with a special lens. This process can be used to create various frames of animation (for a motion effect), or simply to show a set of alternate images which may appear to transform into each other.

The combined lenticular print will show two or more different images simply by changing the angle from which the print is viewed.

Other Print types

There are an array of differing print methods now available using both traditional and contemporary techniques.

Silk screen

A screen is made of a piece of porous, finely woven fabric (originally silk, but typically made of polyester since the 1940s) stretched over a frame of aluminum or wood. Areas of the screen are blocked off with a non-permeable material to form a stencil, which is a negative of the image to be printed; that is, the open spaces are where the ink will appear.

The screen is placed atop a substrate such as papyrus or fabric. Ink is placed on top of the screen, and a fill bar (also known as a flood bar) is used to fill the mesh openings with ink. The operator begins with the fill bar at the rear of the screen and behind a reservoir of ink. The operator lifts the screen to prevent contact with the substrate and then using a slight amount of downward force pulls the fill bar to the front of the screen. This effectively fills the mesh openings with ink and moves the ink reservoir to the front of the screen. The operator then uses a squeegee (rubber blade) to move the mesh down to the substrate and pushes the squeegee to the rear of the screen. The ink that is in the mesh opening is transferred by capillary action to the substrate in a controlled and prescribed amount, i.e. the wet ink deposit is equal to the thickness of the stencil. As the squeegee moves toward the rear of the screen the tension of the mesh pulls the mesh up away from the substrate leaving the ink upon the substrate surface.

Silver Gelatin fibre prints

Prints made from an original black & white negative in the darkroom using chemicals and fibre papers are known as silver gelatin fibre prints. These are the most valuable to collectors, particularly as this now historic method of print making, combined with the fragility of old negatives, mean the prints will be rare. One of the characteristics to these prints is that they do not always dry completely flat and may look a little “wavy” when framed due to the process in which they are made. They are also particularly sensitive to dampness in the air and need to be treated with extra care.

Silver Gelatin RC prints

A silver gelatine RC print refers to an image made on resin-coated paper. These prints are also made from negatives in the darkroom using chemicals, but on plastic-based papers which are easier than fibre papers to work with. They also have the added benefit of drying flat. However, RC prints can be less ‘rich’ in terms of tone and texture than traditional fibre prints.

There are different kinds of digital photo frames on the market. You can get a 7 inch digital frame easily. The manufacturers have the competition in price and function. There are continuous reports about the 3D digital frame which is even the naked 3D digital frame.

In the early June, Japan NewSight presented a 3D display digital frame on US SID 2010. The frame is made with the naked 3D display technology of the company. People can see the stereo image without wearing 3D glasses. The item applies the double convex lens design and the parallax difference is 5.

Even though the professional 3D shooting equipment or 3D picture processing technology is unavailable, the users can process the 3D photo with the product and translating software. NewSight pushes out a 3D photo converting software which can enable the users to convert the photo conveniently.

Aiptek also launches its 3D digital frame on this Computex Taipei. The digital photo frame is upgraded continuously. There is a wide diversity of opinion on the function of digital frame. It will be tested whether the 3D idea will be recognized on the market.

The digital photo frame develops very fast. The different thoughts are given to the frame by different manufacturers. We can gain a glance at the ever innovative ideas of the digital photo frames.

Sony DPP-F700 – built-in printer
There is built-in Dye-sublimation printer on the 7 inch display backside. You can print the photos in two sizes (photo size and postcard size). When you print, you just need to insert the particular type of paper and ribbon which is the Sony produced “super code 2″. The printing of photo size costs about 39 seconds and the one of postcard size is about 45 seconds. The size of the digital frame is 276*150*186mm and the weight is 1.8 kilo.

EXEMODE YASHICA DVF828 – built in scanner
It comes with 8 inch display screen and 1GB internal memory. It can play the image stored in the memory, SD card or memory stick. It can also play music and video. Particularly, it’s able to scan the 4*54×5～10×15cm at the pixels of 300dpi at most. As you put the photo or magazine in the slot and press the scan button, you can complete the scanning and save it. The size is 235*180*85mm and it weighs 0.8 kilos.

GREEN HOUSE-digital frame of card size
The size is 81*48mm and it only weighs 28g. The size of display screen is 1.44 inch. You can connect it to computer with USB interface to start the built-in program and copy the JPEG/BMP/GIF picture saved in the computer. There’s a built-in chargeable battery. It can work for two hours after it’s charged with USB for one and half an hour.

As there is large space on the backside of the display screen, the purchaser can put the LOGO of enterprise and send it to the customer as a gift.

It seems that the digital frames are to the consumer’s needs, but they are not wide spreading. Not only the function, but also the price plays an important role in the purchase.
