Great Color : Equipment

Great color comes after investing in great equipment and after establishing a habitual workflow that you are willing to maintain.
First and foremost you have to count the costs. Great color comes after investing in great equipment and after establishing a habitual workflow that you are willing to maintain. While the current state of technology does not give us great color for free there are a few products that can really help… Read the full article...
Adobe RGB vs sRGB
Over the course of the next few months I will be writing about color, offering some insight into what BIG Images likes to see in computer files, and why. This month I am discussing the difference between two color spaces: Adobe RGB and sRGB.
One of the most oft-debated topics I hear (and take part in) regarding color is which color space to use for images. Before I continue, let me just say that I do not intend to answer this question for all time, but I will offer you the opinion of a professional printer, and tell you why I believe as I do.
Keep in mind that BIG Images is all about getting the best possible print that technology can offer. To do this we need the best possible input into our workflow. Simply put — the more color you give us, the more we can print. This is why BIG Images prefers files in the Adobe RGB color space (there are a few exceptions, but those are beyond the scope of this article). Adobe RGB is simply larger than sRGB, allowing more color information to be stored in an image. To illustrate this I have included a visual comparison of Adobe RGB and sRGB. The white, outer shape, is Adobe RGB and the smaller shape inside it is sRGB. This demonstrates that Adobe RGB is physically larger and can capture more color information than sRGB… Read the full article...

Color Illusions

How Color Can Play Tricks With Your Eye
Color is one of those elusive subjects; it is very difficult to communicate precisely. Many variables, from lighting conditions to the surrounding environment to the age of the viewer, have an effect on the way we perceive color. Some variables in particular change the way colors are perceived when prints become large. In this article I show you some visual aids to demonstrate how a color can be perceived differently simply by changing the surroundings.The Luminance Illusion
Lets start with a simple grayscale example. The image below demonstrates how our perception of depth and shadow effects the way we perceive color. To be more precise, the following illusion will show how the eye perceives the luminance of an object different from the actual luminance values. Press “Play” to reveal the illusion.The Cornsweet illusion: our eyes perceive the luminance of the top and bottom object as different, when they are actually the same luminance, or brightness.
You will see that the top and bottom grey are actually the same value! This effect is know as the Cornsweet illusion. You can read more about it here at Wikipedia.
Discounting the Illuminate
This next illusion demonstrates how the surrounding lighting environment changes the way we perceive color… Read the full article...Color Perception and the Human Body

Part 1: Color Perception and the Retina

figure 1a. Human retina as seen through an opthalmoscope
The blind spot gets its name from the fact that, due to the lack of either photoreceptor (rods or cones), it is literally an area of the retina incapable of detecting light. This is the area in which the long axons of ganglion cells, which carry light information from all parts of the retina, converge to form the optic… Read the full article...
Solvent Ink vs Aqueous Ink
February 09,2007 Filed in: Solutions
“Is it solvent?”
As many of our customers are aware, BIG Images produces prints on huge inkjet printers. In fact, the posters, trade show graphics, banners, and other materials offered by Wide format and Large-format printing companies depend on the same Ink Jet technology found in the office.

The Ink Jet printer is a relatively new phenomenon, replacing dot matrix only 15 to 20 years ago [1] (although the first thermal Ink Jet printer was actually invented in 1977). Two varieties of Ink Jet exist: Thermal and Piezoelectric [2], but ultimately, the principle behind the two are the same; a drop of ink is propelled from the ink head and onto the media at precisely the right time to produce a recognizable image at increasingly impressive speeds.
…a solvent printer is unique in that it heats up the media … leaving the ink embedded in the media!
Trying to apply a polar-based ink to a non-polar surface or vice versa achieves the same unhappy results Read the full article...
New Ink Solutions Increase BIG Images Color

One of BIG Images' printers - a 7 foot wide banner-printer using new outdoor-inks.
New Inks increase color gamut and image strength.
BIG Images recently completed the conversion to a new ink system for its outdoor solutions. These new inks bring a few direct benefits to our customers. These include:
• Increased color gamut—we can now produce better color encompassing about 15% more of the Pantone color range.
• Better weather resistance—waterproof and lightfast outdoors for up to 5 years.
• Increased strength—the new inks stick to the material better, meaning more scratch resistance and longer life
All of BIG Images outdoor solutions are using this new ink starting immediately.
