Silver Halide photo prints, otherwise known as “C” type prints are the Rolls Royce of photo prints. This traditional photographic process is celebrated for achieving vibrant colours, fine details, and long lasting archival quality so that it is the preferred choice for professional and fine art photographers.
Silver halide photo printing, also known as traditional photographic printing, is a process used to create physical prints from digital or film-based images. In the UK, this method has been widely used for decades and is known for producing high-quality, vibrant prints with excellent detail and longevity.
In this article we explain more about silver halide photo printing and why we at PostSnap continue to use this superior method of photo printing when many other photo printers have moved over to using the better value inkjet method of photo printing.
A Brief History
The journey of silver halide or C-type prints began in the mid-20th century. The development of chromogenic colour print processes started in the 1930s with companies like Kodak and Agfa developing the process.
The term "C-type" specifically refers to Kodak's Chromogenic paper. These prints quickly became popular due to their ability to produce high-quality, full-colour images from colour negatives.
By the 1960s, silver halide prints were the standard for colour photographic printing and used extensively in both commercial and artistic applications. Despite the advent of digital photography, Silver Halide photo printing remains a vital process for those who value the depth and richness of true photographic prints.
The Silver Halide Printing Process
It may surprise you to know that creating a silver halide photo print does not involve any ink! This is because silver halide or C type prints are printed on light sensitive photo paper and the photographic image appears when the paper is exposed to light. This method involves several meticulous steps, combining both traditional photographic techniques and modern technology. Here's a detailed look at the process:
1. Photosensitive Paper
The foundation of a C-type print is silver halide colour photo paper. This paper is coated with multiple layers of light-sensitive emulsions, each containing silver halides and dye couplers. These layers are sensitive to different colours of light (red, green, and blue).
2. Image Exposure
The photographic paper is exposed to light through a colour negative, slide, or a digital file. In the case of digital files, a wet lab printer such as a Fuji Frontier is used. These printers convert the digital image into light, exposing the silver halide paper.
3. Chemical Development
The exposed paper undergoes a chemical development process consisting of several stages:
- Developer: This solution reduces the exposed silver halide crystals to metallic silver, while simultaneously creating dye molecules that correspond to the colours of the original image.
- Bleach and Fixer: The bleach solution removes the metallic silver, leaving only the dye image. The fixer then dissolves any remaining unexposed silver halide crystals, stabilising the image.
- Washing: The print is thoroughly washed to remove any residual chemicals, ensuring the longevity and stability of the print.
4. Drying
The final step is drying the print. This results in a stable, vibrant photograph that showcases the depth and tonal range characteristic of silver halide prints.
Benefits of Silver Halide Photo Prints
1. Colour Fidelity and Depth
C-type prints are renowned for their rich, continuous tones and wide colour gamut. The chromogenic process produces vibrant colours and smooth gradients, capturing the subtle nuances of the original image.
2. Fine Detail and Sharpness
The silver halide process can reproduce fine details with remarkable sharpness, making C-type prints ideal for images where precision and clarity are paramount.
3. Archival Quality
When properly processed and stored, silver halide prints are highly durable and can last for decades without significant fading or degradation. This archival quality makes them a favourite for museum and gallery exhibitions, as well as for others who seek long-lasting high quality photo prints for the home or office.
Silver halide vs inkjet printing
Both silver halide printing and inkjet printing have their own strengths and weaknesses, so determining which is "better" depends on your specific needs and preferences.
Here's a comparison of the two printing methods:
- Image Quality: Silver halide printing is known for producing high-quality prints with excellent detail, sharpness, and colour accuracy. The continuous tone nature of silver halide prints results in smooth gradients and rich colors. Inkjet printing can also produce good-quality prints, but the quality may vary depending on the printer, ink, and paper used. Winner: Silver Halide.
- Longevity: Silver halide prints are renowned for their longevity and resistance to fading, with proper care. They are less susceptible to fading from exposure to light and environmental factors compared to some inkjet prints, particularly those produced with dye-based inks. However, pigment-based inkjet prints generally do not last as long as silver halide prints but can offer good longevity when printed on archival-quality paper. Winner: Silver Halide.
- Versatility: Inkjet printing offers more versatility in terms of media options, customisation and accessibility to consumers. Inkjet printers can print on a wide variety of paper types, including glossy, matte, canvas, and specialty papers. Additionally, inkjet printers can produce prints in various sizes, including large-format prints, with ease. Silver halide printing involves specialist print labs and is more limited in terms of print size, media options and typically requires specialised photo paper. Winner: Inkjet
- Cost: The cost of printing can vary depending on factors such as printer, ink, paper, and print size. Generally, inkjet printing tends to be more cost-effective for smaller print runs or prints in custom sizes. Silver halide printing may be more cost-effective for larger print runs or standard print sizes such as 6x4 prints. Winner: Inkjet
- Speed: Silver Halide and Inkjet printing typically offers a similar overall print time. Winner: Even
In conclusion, both silver halide printing and inkjet printing have their own advantages and disadvantages. Silver halide printing excels in image quality and longevity, making it an ideal choice for professional photography and fine art prints. Inkjet printing offers more versatility and customisation options, making it suitable for a wide range of applications and print sizes. Ultimately, the best choice depends on your specific requirements and priorities.
Choosing a Pro Print Lab
If you're considering high quality photos prints for your photography, selecting a reputable pro print lab is crucial. Look for labs that specialise in silver halide or C-type printing and have a track record of producing high-quality work. It's also beneficial to discuss your project with the lab to ensure your vision aligns with their capabilities.
Conclusion
Silver Halide photo prints are a testament to the enduring allure of traditional photographic processes. Their vibrant colours, fine details, and archival quality make them a standout choice for photographers and discerning customers collectors alike.
Whether you’re a professional seeking the best medium for your work or an enthusiast looking to preserve your images in the highest quality, silver halide prints offer a timeless and compelling option.
PostSnap uses the silver halide photo printing process for photo prints due to the superior long lasting results compared to inkjet printing. We offer a wide variety of silver halide photographic prints in sizes from small 4x4 photo prints to super large 20x16 high quality photo prints.
