Do you think I can print a street sign ( 118.5 X 174 cms.) whit my Digilux-2?


How bad will it be?

Gustav, I guess much depends on how far people will be away from the sign. I know that there are specialist printers that can do an amazing job, even with a teeny 35mm neg or a 6MP digital file. In a word, yes, I think it can be done. But much dpends on the use of the sign, the viewing distance and the printer.

That should be possible. I would imagine a street sign would be printed at a far lower resolution than a fine print and even then I have printed crops from the Digilux2 and a Canon 10D to poster size with very good results. The main thing is to do the "upressing"i.e. interpolating the pixels to prevent pixellation using a special program like PhotoZoom or use the old 110 trick in photoshop. That trick is increasing the pixel count in the "resize"option in 110 % steps. It may take a large number of passes, but your edges will remain smooth. Ask your printer what pixel number he recommends. If he can't answer that question find another printer 😉
Let us know how you made out!

I would say the main technique would be to know how much the picture needs to be upressed. If you know the DPI required and the size for the final print PhotoZoom will do that automatically for you.Otherwise it is some basic number crunching.If you deliver the CD to the printer he should be able to do things like screening etc. for you depending on the graphic process he'll be using.

It certainly can be done with decent results. Your resolution should be preferably at least 32dpi. Standing 2 meters away nobody notices. To be sure check with your printer, or print a small sample with the final resolution

In not clear about the "old 110 trick in photoshop" Can some one explain this to me?
I don't own PHOTOZOON.

I got Photoshop CS with the RAW plug in.

Open the resize window, choose 110% in the "pixel"field (lock dimensions etc) and click OK, repeat as many times as necessary to reach the required pixel count.. That way one avoids jagged edges and pixellation.

I can't find it. Don't you mean CANVAS SIZE?

anyway, in the raw window botton left there is a SIZE window. Does it help if I chage it to the bigger size?

normaly is in 2552 by 1920 so I got the option to put it in a maximun of 5120 by 3852.


Thanks for your help

No that will give you jagged edges. In Elements3 (I never use CS-my brain is too limited to understand or ever use the full scope of that program) it is the menu :

"image" > resize > image. Mark "constrain proportions" and "resample bicubic". CS should,however, work the same way.
then pull down "percent" instead of "pixels" and type 110. Click "ok" and repeat as often as needed.
P.S. The rationale behind this trick is to give PS the chance to interpolate the pixels as accurately as possible each time. If you take one big jump that is obviously impossible. It is not necessary to use this gradual approach when downsizing (for instance for the Web) as PS is not interpolating there but losing pixels.
