Printing Jewelry for Catalogue

[leohl1]

Hi,

I am a beginner in Keyshot and would like to ask about printing.
my current setup is Keyshot 7 with Fuji Xerox Docuprint CP405D printer.
I am currently rendering jewelry such as rings and logos and would like to print it in a small dimension (4cm x 4cm for example).
my format is currently using PNG, with a DPI of 300-600.
With a 300 DPI, the resolution is around 600px x 400px and with 600 DPI, the resolution is around 1200px x 750px.
i have tried using different DPI around 300 and 600, using different resolution as high as 3840px x 2400px.
i am also using photoshop and coreldraw to adjust and print my renders.

The problem is, the quality of the print is not crisp and very blurry. i have tried using a regular A4, Glossy and Silky Photo paper but
have the same outcome, still very blurry and low resolution.

can you guys please recommend me a good render output for printing render images in small dimension with crisp and high resolution?
and what type of paper, or perhaps what type of additional settings should i add to make the image more crisp and high resolution?

Thank you.

I think you are getting confused about DPI and other factors.  To get a sharp image you really have to render large, then reduce to the target print size later in Photoshop.

For all of my client product renderings I set the render to 10" (3000 pixels) x whatever. These print great actual size, look great on an overhead projector or large monitor, and are easily resized for web or other uses.

In a few cases I set at HUGE output size, like 72" (21,600) to 120" (36,000) for stuff like trade show backboards.

Remember that when you drop a rendering into Photoshop, it will show up as 72 DPI.  Don't be misled!  Just "Resize" to 300 DPI, with "Resample" unchecked.

Hi Bill G,

Thanks for your reply. by unchecking the "resample", i manage to get a very high quality print.
can you please recommend me a good paper to print jewelry in a very good detail?
Thank you!

I do a lot of high quality giclee printing of KeyShot renderings, and highly recommend MOAB Lasal Exhibition Luster 300.  Luster is almost always the best choice regardless of brand.  I print now on an Epson P800 printer, which is absolutely awesome!  And reasonably priced to boot!

I second Bill's suggestion. Luster paper looks amazing, and because it's not overly glossy you can see the details of the subject matter. I also second Bill's choice of printers. We've had the Epson P800 in my studio for a couple of years now, it produces amazing images and has been as solid as a rock. We bought it with the optional paper roll so we can print 16inch x up to 100ft images if needed.
