From a photography business owner's perspective, the reasons I use a pro lab are: Paper selection - My lab offers me literally a dozen options for paper. Size Matters - Try getting a supermarket to print you a 30x60. ;-) Seriously, though... I rarely print anything smaller than an 8x10, and most of the time bigger than that... Supermarkets are designed to ...

The difference is in the kind of ink particle...the dye or pigment. In your case, PGI-* are pigment inks, and CLI-* are dye (ChromaLife 100 year) inks. Dye inks use dye particles, which are soluble substances. Dye particles tend to be smaller than pigments, lay flatter on the surface of papers, and are often a bit more vibrant in the way they reflect light ...

This is known as lenticular printing. From Wikipedia: How It Works Each image is arranged (slicing) into strips, which are then interlaced with one or more similarly arranged images (splicing). These are printed on the back of a piece of plastic, with a series of thin lenses molded into the opposite side. Alternatively, the images can be ...

The straightforward answer to your question is very simple arithmetic: 32×300 = 9600 and 18×300 = 5400, so 32 inches by 18 inches at 300 dots per inch is 9600 by 5400. However, it gets a little more complicated when you consider a more complicated relationship between pixels and colored dots in your output medium. For details on this, take a look at ...

IP-Slicer perl script can create slices which can stuck together into a ball. You can define the number of slices. The following command will create 12 slices, where the sphere circumference is 1500 pixels. sphere-slicer.pl 12 1500 sampleimage.jpg Sample input: Output (12 images):

Fine art paper is usually made using 100% cotton rag content, is most often acid-free and therefore is suitable for archival purposes since it addresses the problem of preserving documents for long periods (see "How Long Will Your Photo Prints Last?" at PhotoShelter Blog for example). It qualifies as matte paper, thought it certainly has a texture, a look ...

Yes. And it usually depends how much you are paying. The more you pay per print, the more likely there will be a human factor. The big processors(wallmart etc) are unlikely to have the time or skill to go over files before print, its usually a plug-n-go system. I used to run a print shop - and I specialised in 2 things, Bulk prints, and high end art / ...

Color laser printers, especially the big high end office printers, have the color capabilities you need for printing the company logo and the occasional Excel pie chart — but they are truly bad for printing photos. But the good news is that almost any of the current generation of ink jet printers, even the cheap ones, are pretty good at printing photos - ...

OK... I used to run a print shop so i think i qualify to answer this. Any print shop that can print 36x20 inhouse will be using a large format inkjet printer, id say Epson, HP or Canon. Assuming the printer is reasonably new (IE < 4 years) it will almost definitely use good inks - in Epson's case UltraChrome. IF the print shop uses a constant feed ink ...

DPI, or Dots Per Inch relates to the dot density when printing. To help better understand the relationship of DPI to pixel dimensions, take an 800x600 pixel image for example: Using 300dpi, an 800x600 image will print 2.6x2 inches. Using 200dpi, an 800x600 image will print 4x3 inches. Using 100dpi, an 800x600 image will print at 8x6 inches. Notes: As ...

Go to the signage printing industry Sometimes technology intended for one industry is perfect for another industry and this is a case in point. Find a small business near you that specialises in printing large vinyl signs for the advertising industry. Their rates are usually significantly cheaper than photographic printing and the results are every bit as ...

When it comes to print, terms like DPI, resolution, PPI, etc. get thrown around without much care or concern as to what they truly mean. So, before I send you off to a more in-depth answer about DPI, PPI, resolution, and print, a quick summary: DPI: Dots Per Inch A 'dot' is a single element of a pixel On a computer screen, a dot is a single 'sub-pixel' ...

When you say stand in the face of time...exactly how long are you talking? Properly stored, a pigment based ink jet print should last some 150-200 years (according to independent high-intensity lab tests anyway) in great condition, without any extra special care or handling. Now, that does require proper storage, which means kept protected from light and ...

If you've tried enlarging in Photoshop, the first thing is to experiment with the resampling algorithm (photoshop suggests bicubic smoother as the best for enlarging, but I have found it to be image dependent (if you have an image with a lot of edges vs a portrait or landscape). Rather than smoothing, blurring I would suggest using a denoise program next, ...

In theory, one could make great third-party inks, but in practicality, I don't think any of them trade on permanence or color quality. They trade on cheapness. I have a friend who ran out of brand-name ink in a pinch on a project and ended up printing some of it with refills; at first, one had to know in order to tell which was which, but after a week, ...

The lab photo printers are likely to be dye-sublimation, or silver-halide (where the digital image is projected onto normal photo paper) which unlike lithography don't require halftoning, however they still use ink and thus follow the subtractive colour model, so the principal is the same. The reason your colours were off is probably due to CMYK conversion ...

I disagree with John's assertion that the difference depends on how many colours you use, I believe it's possible to dither using a single colour. Halftoning is a term used in the print industry to describe how to reproduce varying tones with significantly fewer inks. It's usually synonymous with amplitude modulation halftoning, where a fixed pattern of ...

Comparing what you see on screen to what you see in a print is not nearly as simple as it may sound. Aside from color (or more precisely, chromaticity), another key difference between gamuts is the white and black point. Similar to the differences in chromaticity between gmauts, the deepest black and the whitest white also differ in extent. This is ...

It's mostly the resolution of the image that affects the sharpening. When using unsharp mask, a radius of 0.1 mm is a good starting value. For an image displayed on a computer monitor at about 100 PPI, that translates to a radius of about 0.5 pixels. Then there are also differences in the media that causes the sharpening to have varying effect. A printing ...

I've given up on making prints at home. I've had various inkjet photo printers over the years, from Canon to Epson to HP. I've never had the high-end models, but I've had some from mid-range on down. And, I got good results from the mid-range ones, and it's true that they offer more flexibility, but the constant problem I had was not printing enough. This ...

It's not the size; it's the shape. Specifically, it's the aspect ratio. That's the relative "squareness" of a photo format. For various historical reasons, there are a lot of different ones, and, as you've noticed, they don't line up. See What historic reasons are there for common aspect ratios? if you're interested in exactly why we ended up in this ...

Let me advocate for offline printing for a second :) I used to print online, but I rely on a local print shop nowadays. I'm not talking CVS or Walmart (in the US), but small, quality print shops run by photographers. Not only is it good for the local economy, but you won't beat that kind of interaction. Print professionals are passionate about what they do, ...

The big trade-off is quality for convenience. Grocery and department stores (like Walmart and Target) are pretty common, so they are fairly convenient to get to. Most of those types of stores are limited to prints that are 8x10 or smaller. Their decent enough for family pictures and sharing physical pictures with your friends. However, I find the ...

It is like normal paper, except that instead of just paper or plastic backing, it has a sheet of Mylar between the paper and the emulsion. It is high gloss, and high contrast, abolutely ROCKS black and white prints. Really gives them a lot of depth when they have a good strong light source.

The two black cartridges you are referring to fall into two main categories: Pigmented and Dye-Based Ink. Your PGI-220BK is pigment based and your CLI-221BK is dye based. Dye-Based Ink Advantages: More vibrant, and more "color" produced Better for text, and printing darker Lower cost Flow better in ink-jet applications Dries quickly Translucent in nature ...

Printing a picture seems like it should be easy but there is a lot more involved when it comes to getting predictable colors from what you see on the screen to the print. The first step is calibrating your monitor. This ensures that your monitor is displaying colors correctly. You can purchase a calibrator from companies such as Colorvision (Spyder series) ...

Image resolution/pixel dimensions are the attributes you should probably be looking for. To find out what numbers you should specify in your requirements, you'll need to decide on the maximum size that you'll want to print an image from the archive, then from that you can derive the minimum resolution that images in the archive should have. For example, if ...
