What do you mean it is made in China is this not upgraded KIS3 machine from same company? or is it some machine made in China?  can you for example use cassette from DKS3 in DKS4.

What is your opinion on the quality of the machine, both print quality, and the built of the machine like racks and so on.

We should get one for presentation in Zagreb, Croatia, probably begining of the next month.

If some off you are near Zegreb at that time feel free to came to the presentation, and when I recive the exact date I will post it here  ;)

We will show the DKS 1890 DM with 3 paper magazines, film scanner IM 1500 Pro and with Epson flatbad scanner V500.

And by the way this DKS 1890 D or DM can do the 30x90cm format but with the small line in between as it makes this format by two time exposing and moving the paper, but this will not make an issue when the prints for photobooks are done as anyway the middle off the paper is were scoring should be done ;)

Now all off the models are coming with double modules (two paper magazines in the machine), but there is the variation for the chemistry regeneration consumption.

DKS 1810 D and DKS 1890 D will use the regeneration from premixed chemistry, but DKS 1810 DM and DKS 1890 DM will use the regeneration from concentrate botles (same like DKS2 and DKS3).

This was strange for me that KIS would do it like that but probably to have more options for the customers.

Also this minilabs are now coming with 3 paper magazines, but there is also posibility to order it as Comfort Pack variant which will include the 6 paper magazines.

Dear friends,

I have a 4 DKS, like the manual to try to understand this new equipment.

In Brazil is not yet available.

I did not know this line in the center of the image, with good eyes can not see this line.

My clients here in Brazil were not happy with this line in the center of the picture.

I do not understand is French? is Chinese? :B

No and I do not know how it is possible to do it with RA-4 paper whic has emulsion on one side only ?

I am aware that it is possible on double side injekt paper and sublimation paper, but with RA-4 paper which is developed in chemistry, I do not know how it is possible to expose it and it should be some special paper with emulsion on both sides !?

I can not compare the DKS 4 minilabs to the Noritsu 37 series minilabs as I do not have experience with Noritsu Minilabs  :o

Regarding the DKS4 Minilabs I can only say that exposure system (LED and LCD and exposure PCB are the same, but lenses are new), and the Software is completely the same as on the DKS3 minilabs and every other parts is changed but in a good way  ;)

Paper magazines have a better design and it is easier to put paper inside and to modify it for any dimensions from 89 to 305mm width paper.

Exposure deck is completely different (measuring cell is still in the middle off the exposure deck), also the racks and dryer section which are now more robust, the gears on the racks are now outside off the racks, the racks main gears are directly connected to the whorm wheel without technical box in between and the filter, heater, replenishment pipes for water and concentrate (DM only) and level sensor (floating) are now on the front side and that is much better concept then before.

Dryer is completely different with much better and more durable soft (black hard sponge type) rollers, which gears are also outside the dryer rack.

Chemical proces is 30s type and during the presentation and on customer site installation I used Kodak Prime SP Lorr setup for the 30s process.

All machines (1810 D/DM and 1890 D/DM) are coming with top and bottom magazine modules as a standard setup and there is no paper visible outside off the cassette (as on DKS 3), but there is the difference in the design off the top and bottom cassettes and they can not be exchange, but with standard setup there is one upper type cassette magazine and two bottom type cassette magazine (but there is also option to buy the machine with 6 cassete magazines).

There is no more densitometer inside off the dryer but with the machine is coming the Barbieri densitometer which is used to read the paper setup but also to make custom paper response.

There is only one knife for top and bottom paper (in the line with the bottom paper and exposure deck).

30x90 format will have small line in between two prints (0.1-0.2mm if everything is setup correctly) and I hope that this will also improve in the future, but anyway this machine intention is to make a prints for large photobooks so you will do the scoring on that line for photobooks and then it is invisible.

So all in all it is the best combination on the end with excellent exposure system and the best software (in my opinion  ;)), and with much stronger mechanics everywhere from cassettes to the exposure deck, racks and dryer together on the market now  :)

Off course there is a lot off improvement to be done, the software is still in progress but even on this point off developing the print quality is excellent  ;)

Just to clarify, it is the same exposure system as on the DKS3, Epson PCB, Piezzo PCB, LED MOT PCB, LCD, PIEZZO, and off course all the settings for the exposure and centering are done in the same way as on the DKS3  ;)

And if I understand correctly there is again the 5 year warrenty on the LCD (never had an issue on this DKS3 LCD, but is is good to have this warrenty  ;))

Hello friends .. Pksaro i wana discuss improvement of print quality by kiss france from dks1 series to dks4 .... Have parts like densitometer or exposure section or lcd or led  which can improve print quality in machines been improved from dks1 to dks2 to dks3 to dks4 ...... I have heard print quality dks2 and dks3 series are almost same ... Is it true .... Thanks

Good afternoon psKaro,

Here in Brazil we are disillusioned with the KIS minilabs.

The difficulty of finding parts are great, especially the import is hampered by our government.

Unfortunately KIS not to intervene and invest in Brazil, will lose a large market.

Currently the old KIS concecionária here in Brazil do not have qualified to serve customers and who possesses KIS KIS minilab is the responsibility of paying high prices for parts that they still have in stock.

So I wonder if you could inform the KIS to give more attention here.

Thank you.

DKS series progressively from 1 to 3(4) have been raising the quality in terms off the output resolution (DPI), but also (in my opinion more important when viewing the prints) in term of color depth.

DKS 1 had resolution from 500+ dpi on (10x15) to 250 dpi (20x30) and 8 bit per color depth (24 bit on all colors), except ciclone/ravage versions which had 10 bit per color depth (30 bit on all colors), but as the print engine was not precise there was visible grid on bigger formats (more visible if that was badly adjusted)

DKS 2 improved greatly in term off the resolution (310 dpi), but with more precise (piezzo movement with microlenses bellow each pixel) print engine and had 10 bit per color depth (30 bit on all colors)

DKS 3 improved even more in resolution terms (340 dpi), also piezzo controlled, but with even more color depth with 12 bit per color depth (36 bit on all colors)

DKS 4 have a same exposure system as DKS 3, with one difference that it has a Barbieri densitometer as a standard equipment with which it is possible to make a custom paper response for every paper/chemistry combination which then makes a better control over print color which is then visible specially when making B&W prints, but off course improvement is visible on color images as well  ;)
