I have an image that’s saved at about 4" x 6". I want to print it at
13 x 17 on roll paper. It appears that I have two options. One is to scale the print size under "Print Preview." The other is to resize the image.
I tried to resize it (and resample it) and print it, and it took all
my computer resources and about 5 minutes just preparing the picture to print. Then the print preview window (Epson 2200) had some different colors than the original photo did.
What’s the best way to do this? I’m very new at this, as you can
probably surmise.
Thanks,
Linda
P.S. please include resolution

Pixel dimensions: 27.8 M;
2600 x 2700 pixels
Resolution is 600 pixels per inch.
You would have to change your resolution from 600 to 158 to get 17.089 inches on your long side. You have two problems here. The first is you will need to crop your image to get to a 13 x17 since your current image is almost square. The second is a PPI of 158 is probably not going to give you the print quality you want. You can try resampling your image upwards in increments of 10%, some people swear by this method though I have never had that good of luck resampling images upwards. At 270 PPI you can get a high quality 8×10 with very little cropping. HTH

If I change the size on the resizing screen, and constrain the proportions, I get 13" by 17.333". But the pixels go up to 10400 by 7800.
Resizing without resampling is always a good idea. I didn’t do the math, but if the result is 158 resolution, I would be tempted to try and print with it as is, the size of the paper being that large.

Juergen,
Resizing without resampling gives a resolution of 207.692.
The intial question was about resizing versus just changing the print size under "Print Preview." What’s the difference?
Uncheck resample and change the 600 to 158 in the resolution box. This should give you an image of around 17.089" x 16.456", you will now need to crop to get to 17×13. How are you changing the size? Step by step please.

Linda,
I honestly don’t know what happens to the resolution when you change the size in Print Preview. I do know what happens using Image >Resize, because you can see the details in the box. Somebody else may want to answer your question about the difference.
Juergen
Print preview does the resampling for you and you lose the control over how it is done. You are attempting to get a large print from a not so large file.

Linda,
I looked at it again. If you cropped the picture to 17×13 you should still be at 158.824 resolution, which, I think, at that size is nicely printable. Juergen
Linda when you said " I’m very new at this, as you can probably surmise" I tried to give you the basic steps to take to upsize your image and to point out that you may be trying to go to large for a high quality print. If that is more info than you wanted I apologize.

Thanks for all your help! And please don’t apologize; there’s never too much information — it just takes a little longer to absorb it.
The step by step of how I was resizing is: Image>Resize>Image Size – then under Document Size, if I type in 13" for the height, the width becomes 17.333. Without resampling, then the resolution goes down to 207 and the pixels stay the same.
Linda,
Everything is clear now. Your image is 3600×2700 (not 2600×2700). So, no cropping is necessary to get close to 17×13. When you resize without resampling you get a resolution of 207.692. My original point was, that you should be able to have a good quality print with that resolution considering the size. A print of that size is not usually viewed from close-up and should be quite satisfactory. If you would still like to go for a higher resolution, 300 being as high as you would possibly want to go, follow Jim’s suggestion to increase it in increments of about 10 percent at a time, using the resampling. I don’t think it is necessary, though.
Juergen
Thanks for all your help! I’ll give it a shot and see how it turns out.
Linda
If you are at 207 PPI and were not working with a 2600 x2700 image as originally indicated your image should print satisfactory using either method. The extra 1000 pixels on the long side make a big difference. If you were correct with the original pixel dimensions your PPI is 158 to get the 17 inches you wanted and you should use the 10% method mentioned earlier. Please let us know which figures you actually have. Good luck.

news:
Thanks for all your help. I think I’ve got it worked out now. The color image I was working on didn’t look so hot enlarged anyway. Today I spent hours and hours trying to get a B&W right. I finally was on the Epson site and found that the printer I have (2200) isn’t compatible with the paper (matte heavyweight.) So I switched to the enhanced matter paper, and WOW! I’m hooked!
May I ask a question about printing resolution?
Most softwares (e.g. Film Factory that comes with Epson2200) allow you to open a jpg file (usually 72dpi from a digital camera), eidt and print at "best quality". I assume that best quality can make use of the top 1440×2880 dpi the printer says it can do. No resampling needed and no drag on PC resources observed.
Using PS Elemnets, you must resize and resample or 72dpi will be used to print which was my first test print looking very poor (even printer setting was at "best quality"). Increasing to 300 dpi is a minumum for 10×8 and to 600dpi shows considerable drag on PC. I can imagine how slow 17×13 with 600dpi can be. But then does it mean that PS Elements can only practically use <=600 dpi printer? I notice that picture package only allows 1200dpi max, if you can wait hours for processing.
Mei
I think you are getting DPI and PPI mixed up. DPI is dots per inch, the number of dots of ink a printer can lay down. PPI is pixels per inch, the number of pixels spread over an inch. You can print a photo at 72 PPI or 1200 PPI on whatever DPI your printer is capable of.

I was thinking the same thing as James when I saw this post, so I agree you’re getting the two confused, which is very common for people new to digital imaging. I have this (in)famous treatise I can post on the subject, but I won’t unless you’re still confused. Let us know if you would like more help with this.
Thank you both James and Beth for the explanation.
I understand your points of distinction between PPI and DPI. Is it correct to say that in a simple software where you have no choice of print DPI but only "best quality" the software will translate a 2592×1944 (my 5m digicam)photo to the highest DPI for printing (using premium photo paper etc)? In PSE2.0 if I choose 250 DPI for a 10×8 print which prints total 5M dots, do I gain anything choosing higher DPI? If no more gain as long as 5M pixels "used up" then a 13×19 print should use 150 DPI (aspect raio issue ignored)? And my Epson2200 will always print at 1440×2800 DPI as long as it’s set to "best quality"?
Apologise for so many questions but I’d like to use the added control (like DPI) in PSE2.0 properly.
thanks,
Mei
No need to apologize, this is one of the tougher concepts in digital imaging for many people to grasp. There is still some confusion as you can not choose 250 DPI in Elements, you can however select PPI in Elements. Here is a link that can help with the basics. It was written for scanners but it also applies to digital images from cameras. This is an excellent website that may bring some clarity to the issue.

Thank you James. I never paid attention to the fact that only "pixels per inch" appear in Elements until you said "you cannot choose 250 DPI in Elements". My understanding is now that DPI is always set by printer options but Elements only set PPI. Some interpolation happens when printing (by printer driver?) coverting PPI to DPI. When do you need to resample to increase pixels? I can see the need to resample down for smaller size.
Thanks a lot.
Mei
Mei, you’re still somewhat confused by the dpi versus ppi thing. You do correctly understand that dpi is referring to printer settings and ppi to images, however there is no "conversion" of ppi to dpi. I’ll give you a linear example that is overly simplified.
Draw a line 6 inches long on a piece of paper and then subdivide it into 6 one inch segments. When you set the image resolution (ppi) to 300 pixels per inch, you are telling Elements that you want it to use 300 pixels to cover each one inch segment of your line. If you have the resolution at 100ppi, you’re telling PSE to use 100 pixels per segment. When you make the decision about the resolution of your image you have decided on the number of pixels that will comprise each square inch of your picture.
Now you want to print, and you want to choose a printing resolution. When you choose that, you are telling your printer how many dots, sprays, splashes, or sprinkles of ink it should use to create each pixel. (The term "dots per inch" is pretty dated compared to today’s printer technology, but it still has a value.) I’m going to pick a printing resolution – dpi – of 1200 per inch because it’s a nice even number to work with. If you choose that, what you are saying is that you want the printer to use 1200 "dots" of ink to create each inch of your image. In simplest terms, you’ve just told it to use four dots of ink on each pixel.
You can create an image with a resolution of 100ppi and print it at the maximum print quality, and you may not like what you get because the image resolution is providing too few pixels per inch to produce a crisp print. On the other hand, you could create an image at 300ppi, put your printer settings at their minimum, and you still may not like what you get. In the first situation you’re not providing enough image detail, and in the second situation you’re not allowing the printer to put down an adequate amount of ink to capture that increased image detail.
Try to shoot for an image resolution of between 200 and 300ppi, and then choose the printer settings as a separate option. The image resolution of ppi and the printer resolution of dpi work in concert to produce an image. Your printer does no interpolation.
The second part of your post relates to resampling. Resampling is not "bad", but the issue of upwards resampling to increase an image size has to be done carefully. When you turn on Resample and tell Elements to increase the size of an image without reducing the number of pixels per inch, you are also telling it to "make up" pixels. Although Elements uses a pretty sophisticated bilear system to create these new pixels, rarely will you get an image with as much clarity after upwards resampling as what you started out with. This concept can get pretty complicated, so it would probably be better if you posted a specific example. In general, until you have a good grasp of upwards resampling, if you’re going to experiment always make sure you keep a copy of your original image!
Camera images, like all digital images, have no inherant ppi. They have pixel dimensions only, which add up to x number of original pixels. With resample OFF, you can put those pixels into a smaller or larger output (ie, printer) area. The smaller the area, the higher the ppi, larger the area, lower the ppi.
Thus a 4×5 print of whatever number of pixels will be much higher resolution than an 8×10 print of the same number of pixels.
Mac
Beth,
your detailed explanation is great! Really excellent.
I think I understand the idea that ppi and printer dpi work in concert to produce good print. I don’t know if "good" setting of my Epson2200 is better than 150dpi. If it is (guess not), does it mean "good" and "best" will print 150ppi image with same quality?
I see that resampling is a more involved topic as original "pixel locations" may be lost in doing so. The picture package, however, does an automatic resampling, right? Is there a way to not resample?
thanks you so much.
Mei
Thank you, Mei; I’m glad it was helpful. (I’ve done this a coupla times!)
With a printer like the Epson 2200, you’re going to get excellent results, so you might have to run a couple of sample pictures through to determine whether you can detect a difference in the quality between "good" and "best." Most people usually choose the highest quality they can get, but I know I’ve used less than the highest quality setting on my printer a few times and have still been satisfied with the results. Some of these things become a matter of personal choice. The subject of the photo can also make a difference in how we perceive the finished picture, and less-than-perfect results are also less obvious if a picture is going to hang on a wall and be viewed from a distance.
There are a lot of general guidelines in digital imaging, but sometimes it’s just not possible to tell someone exactly what they need to be doing with their specific equipment. What looks good to me may look horrible to you, and vice versa. A certain amount of experimenting has to occur over time, and you’ll gradually get a feel for how far you can "push" one way or the other. Printing at a resolution and printer setting that’s too high will simply waste time and system resources. Printing at a resolution and printer setting that’s too low will give you disappointing results. There’s a sweet spot somewhere, and it won’t take you long to find it, but I don’t know what it is through your eyes. 🙂
Yes, Picture Package will resample, and that’s one of the reasons I don’t use it. However, you can bypass that automatic resampling by doing all of your resizing first, which will give you a lot more control. I also try not to resample upwards unless I do it very carefully and by hand, but resampling downwards doesn’t really do any harm because you’re just compacting the pixels into a smaller area.
Give me an example of the size and resolution of an original image from your camera and tell me what size print you want. I’ll use that as a base for resizing, which will make the explanation easier in the long run.
thanks Beth and Mac.
I’ve been experimenting with lots of prints of different settings. I think I’m getting there…
Thanks again Beth.
Mei
