Best Print Resolution

[rubens_t_vora]

Dear,

 

After reading some excellent reviews from "Fine Art Printing" Uwe Steinmueller and Juergen Gulbins, I think this

book must be seeing for those whoe really want understand in low level the best technics. But there were a important

missing in this book. What are the best steps to preserv the best integrity from Raw files and them print.

 

If you in Lightroom and could send your Raw file directly to printer is one option. In second, you can choose edit in

Lightroom and go thru Photoshop in TIFF convertion. And third way is export in DNG thru bridge and still in

photoshop. Question - Could anyone rate this ways, aproaching best printing resolution?

 

Thanks, Rubens

Anything above 300 dpi on a print is probably a waste of ink. Even the high resolution large prints in "coffee Table" books are printed at 3oo dpi.

Hi Wayne, It's highly recomended read this book. If you are going to a Art Print you can go for 720 DPI in Epson printers. Tks

Rubens just do what you did with the images in your portfolio at PN. Especially the first one looks fine for

printing.

 

Raw files are like negatives if you send those out you have little control of the colors, the saturation, the

luminescence etc. Of course you could try and find an expert who is more capable than you but be prepared to

spend a large sum of money and a few visits to the printer to cross check the results :-)

 

Your question about printing resolution is hard to understand. Perhaps it is trivial. You can adjust in most

imaging software the resolution to your liking independent of your other adjustments in post processing. If you

prefer 720 DPI and find someone who can print at this

resolution just set the dpi to 720. Depending on the print size you may get very large files. Depending on the

viewing distance much lower resolution is required as said above.

Hi walter,

 

Sorry for my misunderstanding. In fact and directly to the point, There is some compression in TiFF format and either in DNG format. So doesn't it effect your final resolution, that affects even your final printing? If doe not we were using JPeg for every shots. Thanks!

No there is no compression in TIFF format, unless you are talking about a TIFF file with LZW compression (a lossless compression format). TIFF is the de-facto standard for image archiving.

Rubens DNG is just another RAW format. It is promoted by Adobe as a general raw format. As Dave pointed out TIFF

is an standard file format for images. There is a not very effective (in file size) but lossles compression (LZW)

or ZIP (offered by some software) available.

 

JPG files are used to obtain some more compression. The format is very flexible in the degree of compression at

the expense of information loss.

 

Printers usually want either TIFF or JPG files for printing because these are final products of image processing

and it is your responsibility to make all adjustments. The printer just tries to print the images as close as

possible to the image you supply.

 

Since you are already reading excellent books and recommend reading I suggest you look for introductory books

about image processing and RAW conversion. There are for example some very good books from Adobe on the topic.

This will give you a basic understanding of file formats, RAW image conversion, a color aware workflow from RAW

image to print or an image for screen representation.

Hi Walter,

Very pleased with your attention. Anyway, there is no standardization for this concepts as far as I red. To jpg no dobts about. DNG is not adopted entirely and TIFF is a desired for most opinions. In fact, after 10 books reviwed each author has a diffrent aproach betwen TIFF and DNG.

 

Thanks, Rubens
