You’re welcome 
The write up only has sheet info from sheets that I’ve seen, but it’s not unusual for multiple print facilities to create a set.
Typically Belgium handles European languages, while USA facilities handle Asia & South America, and every facility makes English cards.
Since Pokemon was also using an Australia facility, I’d expect them to do English & Asian cards.
GPS Colour Graphics did English, and also shipped stuff to eastern Europe.
But this is just a rough guideline.
I’ve never looked, but usually there’s a clue on the fine print of the packaging.
I wouldn’t be surprised if the main print run of boosters was handled by a large print facility, and a smaller print run of theme decks which don’t sell well was handled by another smaller print facility.
WotC did that a lot in the USA about a decade ago, which isn’t their Pokemon era, but there’s probably an underlying reason such as production efficiency or cost, which makes it reasonable regardless of who is handling the brand.
How is it different? At some point, WotC changed to 200 LPI (higher resolution than before, which creates smaller diameter rosette circles).
Whatever change you’re seeing could be caused be a software upgrade, or just using different settings inside the software.
The next chapter of the timeline…
Feb 28 2002 English Neo Destiny 113 cards WotC
Again there are both 1st Edition and Unlimited versions of the cards.
This is the last WotC set to have 1st Edition cards.
Mar 8 2002 Japanese The Town on No Map (Aquapolis) 92 cards Media Factory
It did have both 1st Edition and Unlimited versions of the cards.
May 24 2002 Japanese Wind from the Sea (Aquapolis) 90 cards Media Factory
It did have both 1st Edition and Unlimited versions of the cards.
May 24 2002 English Legendary Collection 110 cards WotC
This set was not released in Japanese. It doesn’t have a 1st Edition
version, it only has Unlimited cards.
2002 English The “For Position Only” cards were created while developing the
Expedition Base Set, during the printing of the Legendary Collection.
They were packaged inside Legendary Collection booster wrappers, and
were not intended for the public. They came from a WotC employee
who had saved them from destruction.
Aug 24 2002 Japanese Split Earth (Skyridge) 91 cards Media Factory
It did have both 1st Edition and Unlimited versions of the cards.
Sep 15 2002 English Expedition Base Set 165 cards WotC
Expedition press sheets are dated July 11th 2002 and August 1st 2002.
This set was delayed until September to make sure that the Game
Boy Advance e-Reader was available to use the cards with.
Due to additional licensing fees that WotC had to pay for the dot codes
on the cards, pack size was reduced to 9 cards. Additionally, the
e-Reader wasn’t tournament legal, and never became overly popular
outside of Japan. The European release was further delayed for the
e-Reader to become available, which never happened, and the card set
was eventually released in Europe in April 2003.
Oct 4 2002 Japanese Mysterious Mountains (Skyridge) 91 cards Media Factory
It did have both 1st Edition and Unlimited versions of the cards.
2002 Pokemon USA hired away WotC senior vice president Richard Arons, WotC vice president Rene Flores, and several other WotC executives.
Pokemon USA hired at least seven former Wizards employees to work
on the Ruby/Sapphire trading-card game edition, including Wizards’
former art director, senior graphic designer, business manager, events
marketing director and project management director. All had signed
nondisclosure agreements prohibiting them from using or disclosing
confidential information about Wizards to third parties.
Jan 15 2003 English Aquapolis 182 cards WotC
Jan 31 2003 Japanese Expansion Pack (EX Ruby & Sapphire) 55 cards Media Factory
It did have both 1st Edition and Unlimited versions of the cards.
Mar 2003 Pokemon USA refused to allow WotC to release the Legendary II
expansion set which was scheduled for late spring, or the Jamboree
expansion set which was scheduled for later in the year, despite WotC
having spent considerable time and money developing them.
Pokemon USA also informed WotC that they had not been chosen to
manufacture and distribute the upcoming Ruby/Sapphire Edition, and
that the WotC contract with Pokemon scheduled to expire later in the
year, would not be renewed.
WotC encouraged Pokemon players to contact the Pokemon Company
and ask them how tournaments and organized play would be handled in
the future. As a result of these questions from the public, Pokemon
offered to approve release of the Legendary II set if WotC would share
confidential information about tournament players and provide free
marketing support. WotC declined this offer.
Apr 18 2003 Japanese Miracle of the Desert (EX Sandstorm) 53 cards Media Factory
It did have both 1st Edition and Unlimited versions of the cards.
May 12 2003 English Skyridge 182 cards WotC

Jun 18 2003 English EX Ruby & Sapphire 109 cards Pokemon USA & Nintendo
This was released by Nintendo while WotC still had the manufacturing
and distribution contract.
Jun 25 2003 Japanese Rulers of the Heavens (EX Dragon) 54 cards Media Factory
It did have both 1st Edition and Unlimited versions of the cards.
Sep 17 2003 English EX Sandstorm 100 cards Pokemon USA & Nintendo
This was released by Nintendo while WotC still had the manufacturing
and distribution contract.
Oct 1 2003 The day after its licensing agreement ended, Wizards of the Coast
filed a lawsuit against The Pokemon Company, two Pokemon USA
employees, and Nintendo of America Inc, accusing Nintendo of breach
of contract, stealing trade secrets and technologies, and violating its
intellectual property, including a patent on the “trading card game
method of play” that Magic: The Gathering made famous. The suit
also accuses Pokemon USA of using Wizards’ proprietary information to
solicit Wizards’ distributors, vendors and customers.
Oct 24 2003 Japanese Magma VS Aqua: Two Ambitions (EX Team Magma vs Team Aqua)
80 cards Media Factory
It did have both 1st Edition and Unlimited versions of the cards.
Nov 24 2003 English EX Dragon 100 cards Pokemon USA & Nintendo
Dec 29 2003 Nintendo folded, settling the WotC lawsuit out of court for an
undisclosed sum and the two companies went their separate ways.
In 2003, the contract between Pokemon and WotC came to an end.
It was a messy end.
Pokemon had originally made the deal with WotC and their original CEO Peter, and it was a good relationship. But over time, Hasbro took control, the CEO changed along with most of the employees, and Pokemon wasn’t happy with the relationship anymore. It didn’t help that Pokemon sales collapsed during 2001.
Preparing for the end of the contract, Pokemon resorted to industrial espionage, head-hunting key WotC employees, and stealing trade secrets, trying to learn how WotC did everything, so that Pokemon could do it themselves without WotC.
During 2002, Pokemon USA hired away WotC senior vice president of non-MTG card games Richard Arons, WotC vice president of marketing Rene Flores, and several other WotC executives. Pokemon hired at least seven former Wizards employees to work on the Ruby/Sapphire trading-card game edition, including Wizards’ former art director, senior graphic designer, business manager, events marketing director and project management director. All had signed nondisclosure agreements prohibiting them from using or disclosing confidential information about Wizards to third parties.
March 2003 is when things really fell apart. Pokemon USA refused to allow WotC to release the Legendary II expansion set which was scheduled for late spring, or the Jamboree expansion set which was scheduled for later in the year, despite WotC having spent considerable time and money developing and translating both of them.
Pokemon USA also informed WotC that they had not been chosen to manufacture and distribute the upcoming Ruby/Sapphire Edition, and that the WotC contract with Pokemon scheduled to expire later in the year, would not be renewed.
WotC realized that Pokemon USA had forgotten to steal the player rankings and organized play data for Pokemon tournaments, and used this to create public pressure against Pokemon USA. WotC encouraged Pokemon players to contact the Pokemon Company and ask them how tournaments and organized play would be handled in the future. As a result of these questions from the public, Pokemon offered to approve release of the Legendary II set if WotC would share confidential information about tournament players and provide free marketing support. WotC declined this offer.
The last Pokemon release for WotC, was Skyridge in May 2003. The order to print Skyridge, was probably placed in February, before WotC knew the Pokemon contract wasn’t going to be renewed.
Then Pokemon USA & Nintendo did something really dumb. They released EX Ruby & Sapphire in June 2003, while WotC still held the manufacturing and distribution contract.
They didn’t wait until the WotC contract expired, so it was very clearly breach of contract.
Pokemon USA & Nintendo repeated this mistake in September when they released EX Sandstorm.
October 1st 2003, The day after its licensing agreement ended, Wizards of the Coast filed a lawsuit against The Pokemon Company, two Pokemon USA (ex-WotC) employees, and Nintendo of America Inc, accusing Nintendo of breach of contract, stealing trade secrets and technologies, and violating its intellectual property, including a patent on the “trading card game method of play” that Magic: The Gathering made famous. The suit
also accused Pokemon USA of using Wizards’ proprietary information to solicit Wizards’ distributors, vendors and customers.
Pokemon USA & Nintendo didn’t have a chance of winning this lawsuit with the overwhelming evidence. Nintendo folded, settling the WotC lawsuit out of court for an undisclosed sum and the two companies went their separate ways.
It was expensive, but Pokemon USA & Nintendo continued using the same manufacturing facilities and distributors that WotC used.
All the Pokemon people at WotC, are out of a job.
Time to clean out their desks and empty their offices.
Hasbro doesn’t allow WotC employees to sell anything that’s made by WotC, not even cards from their personal collection.
But employees are allowed to trade with each other.
There’s also a “free table” near the kitchen area, for anything that you don’t want anymore. Maybe you tried a new game and didn’t like it, you can leave it on the free table for someone else to try. Maybe you brought cupcakes to share at work, they go on the free table. Maybe you got a new desk lamp, so the old one goes on the free table.
When Pokemon stopped being made by WotC, and everyone was cleaning out their desks to get rid of stuff that wasn’t needed anymore, a lot of Pokemon stuff ended up on the free table.
